Inorganica Chimica Acta is an established international forum for research in all aspects of Inorganic Chemistry. Original papers of high scientific level are published in the form of Articles (full research reports), Notes (short research reports) and Reviews.

Topics include: synthesis and reactivity of coordination and metallorganic compounds; structural, spectroscopic and bonding properties of inorganic molecules; catalytic reactions promoted by inorganic systems; electron transfer reactions involving inorganic systems, including electrochemical investigations; reaction mechanisms of nucleophilic substitutions or electrophilic attacks on inorganic or metallorganic compounds; basic studies of bioinorganic molecular models. Crystallographic work will only be considered if there is a significant chemical interest.

Abstracting services

This journal is cited by the following Abstracting Services: Cahiers Bibliographiques de Chimie, Chemical Abstracts, Current Contents, PASCAL / CNRS, Physikalische Berichte, Science Citation Index.

Types of contributions

Articles
These should describe significant complete studies. They are not limited in length, however, authors are requested to omit routine data (see Supplementary material mentioned on page five). An abstract of 100-200 words should be included which should be understandable in isolation, reference to the main text is thus not permissible.

It is preferred that the various sections which constitute the Article be put in the following order: Abstract; Introduction; Experimental; Results and discussion; Supplementary material (if necessary); Acknowledgement(s) (if necessary); References.

The title and abstract for an article provide most of the information upon which indexing is based. The title of an article should involve names, not formulae, of chemicals when feasible and should not contain abbreviations.

Notes
A Note should be a report in full of a significant work that is limited in scope; it should not exceed 2000 words. Extensive speculative interpretation in a Note is inappropriate. Notes should include an abstract.

Submission of contributions
From now on, papers should be submitted through Elsevier Editorial System (EES), which can be accessed at http://www.elsevier.com/locate/ica. The system automatically converts source files to a single Adobe Acrobat PDF version of the article, which is used in the peer-review process. Please note that even though manuscript source files are converted to PDF at submission for the review process, these source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by e-mail and via the Author's homepage, removing the need for a hard-copy paper trail.

All submissions should be accompanied by a graphical abstract (pictogram and synopsis) for the Contents List. If crystallographic results are reported, authors are encouraged to validate (via the checkCIF service developed by the International Union of Crystallography (IUCr) available at http://checkcif.iucr.org) and requested to deposit crystallographic data (usually, by sending a CIF file to deposit@ccdc.cam.ac.uk prior to submission).

Regular manuscripts should be submitted either to Professor Lippert or Professor Puddephatt. Manuscripts intended for Special Issues should be submitted to the appropriate handling editor, usually Professor Belluco.

Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, without the written consent of the copyright holder.

Upon acceptance of an article by the Journal, the author(s) will be asked to transfer the copyright of the article to the publisher. This transfer will ensure the widest possible dissemination of information.

Funding body agreements and policies Elsevier has established agreements and developed policies to allow authors who publish in Elsevier journals to comply with potential manuscript archiving requirements as specified as conditions of their grant awards. To learn more about existing agreements and policies please visit http://www.elsevier.com/fundingbodies

Author Enquiries. For enquiries relating to the submission of articles (including electronic submission where available) please visit this journal's homepage at http://www.elsevier.com/locate/ica . You can track accepted articles at http://www.elsevier.com/trackarticle and set up e-mail alerts to inform you of when an article's status has changed. Also accessible from here is information on copyright, frequently asked questions and more. Contact details for questions arising after acceptance of an article, especially those relating to proofs, will be provided by the publisher.

Manuscript Preparation
Language: Authors who require information about language editing and copyediting services pre- and post-submission please visit http://www.elsevier.com/wps/find/authorshome.authors/languagepolishing or contact authorsupport@elsevier.com for more information.

Some flexibility of presentation will be allowed, but authors are urged to arrange the subject matter clearly under such headings as Introduction, Experimental, Results, Discussion, etc.

All contributions should include a concise, informative Abstract and a maximum of six Keywords.

References should be numbered consecutively throughout the text and should be collected together in a reference list (headed References) at the end of the paper. All equations, tables and legends should be numbered consecutively and separately throughout the paper.

Illustrations.
Line drawings should be submitted in a form suitable for reproduction. Illustrations can be printed in colour at no cost to the Author when they are judged by the Editor to be essential to the presentation.

If together with your accepted paper, you submit usable colour figures, then Elsevier will ensure, at no additional charge, that these figures will appear in colour on the Web (e.g., ScienceDirect and other sites) regardless of whether these illustrations are reproduced in colour in the printed version.

Please note: Because of technical complications that can arise in converting colour figures to "grey scale" (for the printed version should you not opt for colour in print), please submit in addition usable black-and-white files corresponding to all the colour illustrations. Information concerning colour illustrations and possible costs to the author can be obtained from the Publisher.

Graphical Abstracts.
Please note that the Contents Lists will contain Pictograms and Synopses. The authors are therefore asked to provide us with a drawing or reaction scheme illustrating their work and a short Synopsis of maximum 50 words.

Proofs
Authors will receive proofs by e-mail (PDF) or fax, which they are requested to correct and return as soon as possible. No new material may be inserted in the text at the time of proof-reading. A Note added in the proof must be dated and the author must have requested and received the Editor's approval.

Offprints
The corresponding author, at no cost, will be provided with a PDF file of the article via e-mail or, alternatively, with twenty five free paper offprints. The PDF file is a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use.

There are no page charges.

Safety notes
Authors should emphasize any unexpected or new hazards encountered in experimental work reported. Perchlorate salts of metal complexes with organic ligands are potentially explosive. Authors are requested to place a cautionary note regarding the hazards of perchlorate complexes.

Supplementary material
In order to reduce page space occupied by published papers, it is preferred that all routine results and/or experimental practice be retained by the author or deposited in one of the recognized data retrieval centres. A note informing the reader that further details are available and their location should be introduced under the heading "Supplementary material"

Product yields and melting points
Yields of products obtained in reactions which are reported should be given in terms of g or mol as well as in %. If it is not obvious, it should be stated on what reagent the % yield is based. It should be made clear whether the yields reported are of crude product (specify purity, if possible) or of pure product. If yields are obtained by gas chromatography, details of the yield determination should be provided. Authors are encouraged to provide melting points (and decomposition points) for all new solid compounds.

Spectra
Although routine spectra will not be published, important spectral results can be presented in carefully planned figures. If such spectra have already been published then reference to these will be sufficient. Where there is a group of similar compounds with unimportant differences in their spectra then the presentation of one spectrum is adequate.

Microanalyses
Sufficient evidence should be provided to establish the identity and purity of new compounds. This should, in general, include elemental analyses, for which there is agreement between found and calculated values of 0.4%. Where such data is collected in tables it may be published or the editor may request it to be deposited as supplementary data along with other analytical material.

Crystal structure studies
Crystallographic work will be assessed mainly for its chemical interest. Thus crystallographic work carried out as part of a wider chemical study should not normally be submitted for publication separately from the results of that study. However, papers reporting only the results of crystal structure determinations may be accepted for publication provided that these results are considered to possess specific chemical significance.

Crystal structure studies submitted as Articles
Structure reports should include each of the measured and calculated quantities specified below. Although provided for review purposes, only a limited amount of this material will be included in the published text. All refined parameters or quantities calculated from these parameters should be accompanied by their estimated standard deviations (e.s.d.s).

Abstract
Crystal data should not be given in the abstract. It will suffice to note in the abstract that the structure of a given compound has been determined by X-ray diffraction and to point out any noteworthy structural features.

Experimental
The description of the data collection and structural analysis should be as brief as possible for routine structure determinations. A description of these aspects of the work can usually be accomplished in one short table and should include the following information: (a) chemical formula, source of material and habit; (b) lattice constants, wavelength assumed in their calculation, temperature at which they were measured; radiation used in intensity measurement; type of filter or monochromator; (c) space group (method of distinguishing between groups with the same absences); (d) crystal dimensions, – range of absorption (or transmission) factors; method of correcting for absorption; (e) type of diffractometer, diffraction geometry, conditions for collecting reflections (i.e. 2 – range and sign(s) for hkl data collected); (f) number of reflections measured, number of independent reflections when multiple forms of the data have been collected; (g) final R factors (weighted and unweighted). A goodness-of-fit or the so-called "S" value should also be given. A brief outline of the method used for the structure solution should be given. Computer programs and source of atomic scattering factors and anomalous dispersion (? f' and – f"") should be appropriately referenced. Tests for the chirality of a non-centrosymmetric crystal (assuming that anomalous scattering is included) and corrections for extinction should be included when appropriate. Designation of atoms refined with anisotropic thermal parameters, treatment of hydrogen atoms, and geometrical constraints should be described.

Structural Results:
A clear distinction should be made between material to appear in print and material for the referees which should be sent as "Supplementary material" directly by the authors to both the Editor and the Cambridge Crystallographic Data Centre or to another recognized data retrieval centre.

For Publication in the Journal:
In addition to the discussion of the structure the following should be provided: (a) a table of selected bond lengths and angles, with e.s.d.s; (b) drawings of crystal or molecular structures, made with the non-crystallographer in mind. If the structure was refined anisotropically, the orientations and magnitudes of vibrational ellipsoids should be displayed.

For the referees and/or for deposition:
Prior to the submission of the manuscript, the author(s) should validate and deposit files in Crystallographic Information File (CIF) format. Validation should occur before deposition via the "checkCIF" service developed by the International Union of Crystallography (IUCr) available at http://checkcif.iucr.org. Authors are strongly recommended to take advantage of this service and submit manuscripts accompanied by an IUCr validation report to help the referees reviewing the manuscript. Authors should deposit with the relevant Date Centre the data corresponding to each structure to be reported in the intended publication (for metal organic structures: The Cambridge Crystallographic Data Centre (CCDC), by e-mail; deposit@ccdc.cam.ac.uk; for inorganic compounds: Fachinformationszentium Karlsruhe (FIZ), by e-mail; crysdata@FIZ-Karlsruhe.de.

Crystal structure studies submitted as Notes
All of the material required for a full paper, including the structure factor table, should be submitted for examination by the reviewers and the Editor. The manuscript itself should provide the following: chemical formulae; lattice constants and standard deviations, crystal system, space group (Hermann-Mauguin symbol), and number of formulae per unit cell (Z); intensity measurement method used and temperature; refinement method and final R factor on F (if on F 2, state explicitly); description of the overall structure, including bond lengths and angles of major interest, in tabular form or on the figure. An ORTEP or equivalent projection of the molecular structure with thermal ellipsoids should be provided. All other information accompanying the structure determination should be submitted in a form suitable for deposition as "Supplementary material". If publication of more complete crystallographic details is planned, this should be stated in a footnote with the authors' names and the intended journal of publication included, if possible.

Contributions are accepted on the understanding that the authors have obtained the necessary authority for publication. Submission of an article must be accompanied by a statement that the article is original and unpublished and is not being considered for publication elsewhere. Upon acceptance of an article by the Journal, the author(s) will be asked to transfer the copyright of the article to the publisher. This transfer will ensure the widest possible dissemination of information.
Authors are reminded that delays in publication may occur if the instructions for submission and disk and manuscript preparation are not strictly followed. Authors are strongly recommended to submit disks to aid rapid processing. To facilitate communication, authors are requested to provide their current e-mail address, phone and fax numbers.

There are no page charges

Preparation of manuscripts on disk
Main text
Articles prepared using any of the more popular word-processing packages are acceptable but please note the following points.

•Submissions should be made on a double-density or high-density 3.5" disk.

•The disk format, word-processor format, file name(s) and the title and authors of the article must be indicated on the disk.

•The disk must always be accompanied by a hard-copy version of the article, and the content of the two must be identical.

•The disk text must be the same as that of the final refereed, revised manuscript.

•Disks formatted for either IBM PC compatibles or Apple Macintosh are preferred. If you can provide either of these, our preference is for the former.

•The article must be saved in the native format of the word processor used, e.g. WordPerfect, Microsoft Word, etc.

•Although most popular word processor file formats are acceptable, we cannot guarantee the usability of all formats. If the disk you send us proves to be unusable, we will publish your article from the hardcopy.

•Please do not send ASCII files as relevant data may be lost.

•There is no need to spend time formatting your article so that the printout is visually attractive (e.g. by making headings bold or creating a page layout with figures), as most formatting instructions will be removed upon processing.

•Leave a blank line between each paragraph and between each entry in the list of bibliographic references.

•Tables should preferably be placed in the same electronic file as the text. Authors should consult a recent issue of the Journal for table layout.

Graphics
General
Although there are still a large number of technical difficulties to overcome, we are processing graphic files in a growing number of cases. Both scanned and computer-generated illustrations, either in colour or black and white are acceptable.
Requirements
The following requirements are to be met:
Hard copy in all cases: Since we cannot a priori guarantee the usability of your graphic file(s)high quality hard copies of all illustrations must accompany the accepted printout of the manuscript in all cases.
Disks: Files should preferably be submitted on disk, either IBM or Macintosh. Submission via e-mail is not recommended for large files.
Format: TIFF or EPS files are preferred. TIFF files should preferably be compressed, but only LZW (Macintosh) compression is acceptable. Please note that corrections in EPS figures are only possible if they have been prepared with Adobe Illustrator 3.0 or higher versions. The usability of other formats is to a large extent dependent on the information you supply us with concerning the soft - and hardware used. It is a good idea to put the relevant information in the header of the file.
Resolution: Drawings made with Adobe Illustrator and Aldus Freehand (Macintosh) and CorelDraw (IBM/DOS) generally give good results. Drawings made in WordPerfect or Word generally have too low a resolution; only if made at a much higher resolution (1000 dpi) can they be used. Files of scanned line drawings are acceptable if done at a minimum of 1000 dpi. For scanned halftone figures a resolution of 300 dpi is sufficient. Scanned figures compressed with JPEG usually give no problems. Please note that scanned figures cannot be enlarged, only reduced.

Estimation of length
For a rough estimate of the final length of their printed article authors should count 850 words per full two-column page or four illustrations per page.

Keywords
A maximum of six keywords should be indicated below the abstract to describe the contents of the manuscript. Keywords should be selected, if appropriate, from the following classes: theoretical methods, experimental methods, phenomena, materials, and applications.

Graphical abstracts
Please note that the Contents Lists contain graphical abstracts: pictograms and synopses. The authors are therefore asked to provide us with a drawing or reaction scheme illustrating their work and a short Synopsis of maximum 50-60 words. The small figure should measure 50x43 mm for direct reproduction or a maximum of 83x72 mm for reproduction by 60%.

Colour illustrations
Illustrations can be printed in colour when they are judged by the Editor to be essential to the presentation. Generally, the publisher and author will each bear part of the extra costs involved. The charge to be passed on to authors of articles containing colour figures is EUR 635.00 for the first page containing colour and EUR 318.00 for each additional page containing colour. Authors located in Europe or Japan will be billed in Euros, while authors located outside Europe or Japan will be billed in US dollars.

Product yields and melting points
Yields of products obtained in reactions which are reported should be given in terms of g or mol as well as in %. If it is not obvious, it should be stated on what reagent the % yield is based. It should be made clear whether the yields reported are of crude product (specify purity, if possible) or of pure product. If yields are obtained by gas chromatography, details of the yield determination should be provided.
