The International Journal for Inorganic and Organometallic Chemistry

General
Polyhedron publishes full length papers, commissioned reports and symposia-in-print. All contributions should conform to the Aims and Scope of the journal. All contributions shall be rigorously refereed.

Papers - should be substantial, completed pieces of original research in inorganic and organometallic chemistry which have special significance, general interest and which, in addition are presented clearly and concisely.

Reports - are specially commissioned critical reports reviewing research results of topical importance. Reports will be commissioned by the Editorial Board from recognized authorities in the appropriate fields.

Symposia-in-Print - are collections of original research papers brought together to cover timely areas of inorganic and organometallic chemistry. For each, a Symposium Editor will invite authors active in the field to submit papers.

Submission of contributions
Submission of both regular and special issue articles to this journal proceeds totally online. Authors are encouraged to submit their manuscript to the appropriate (Regional) Editor via the homepage of this journal at http://www.elsevier.com/locate/poly.

On the right hand side under the heading For Authors, you will find Submit your article. After logging in, use the dropdown menu to make your selection:

Papers from the Americas: G. Christou
Papers from the rest of the world: C.E. Housecroft
Papers from China, initial submission: T.C.W. Mak
Papers from Australia: G. Christou, C.E. Housecroft
Polyhedron Reports: G. Christou
Symposia-in-Print: G. Parkin

Use the following guidelines to prepare your article. Via the Polyhedron homepage ( http://www.elsevier.com/locate/poly) you will be guided stepwise through the creation and uploading of the various files. 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 authors are requested to include complete contact details including their fax number and e-mail address.

Note: all submissions should be accompanied by a graphical abstract (pictogram and synopsis) for the Contents list. Crystallographic data need to be validated (via http://checkcif.iucr.org, see details below) and deposited (usually, by sending a CIF file to deposit@ccdc.cam.ac.uk prior to submission, see details below).

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. Standard ethical guidelines for journal publication can be found under http//www.elsevier.com/wps/find/intro.cws_home/ethical_guidelines.

Manuscript preparation
Articles must be written in good English.
Language polishing. 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. Please note Elsevier neither endorses nor takes responsibility for any products, goods or services offered by outside vendors through our services or in any advertising. For more information please refer to our Terms & Conditions http://www.elsevier.com/wps/find/termsconditions.cws_home/termsconditions.

File formats. We accept most word processing formats, but Word, WordPerfect or LaTeX is preferred.
Manuscripts should be prepared with numbered lines, wide margins and double spacing. Section headings to be used are Introduction, Experimental, Results and Discussion, Conclusion, Supplementary materials, Acknowledgements, References.

Corresponding author
Clearly indicate who is willing to handle correspondence at all stages of refereeing and publication, also post publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. This corresponding author should be clearly indicated by an asterisk.

Graphical abstract
When submitting your article please provide a graphical abstract. The graphical abstract is used for the table of contents. It is composed of a 50 word synopsis and a pictogram: one figure representative of the work described. Maximum final dimensions of the pictogram are 5 x 5 cm: bear in mind readability after reduction, especially if using one of the figures from the article itself. The graphical abstract is submitted as a separate file during the online submission process.

Abstract
A concise and factual abstract is required. The abstract should briefly state the purpose of the research, the principal results and major conclusions. An abstract is often presented separate from the article, so it must be able to stand alone

Keywords
Immediately after the abstract provide a maximum of six keywords.

Equations, tables and legends
These should be numbered consecutively and separately throughout the paper. The presentation of tables, graphs and formulae should be kept to an absolute minimum, and where possible the results from a series of investigations should be in table form or as a graph. The same data should not be presented in both tables and figures or given in the Discussion as well as the Experimental section.

Illustrations
Submitting your artwork in an electronic format helps us to produce your work to the best possible standards, ensuring accuracy, clarity and a high level of detail.
Graphics and photographs may be embedded in the text of the manuscript at first submission. If you do so please note that separate graphic files will always be required for proof production when a manuscript is accepted for publication. Graphics should be submitted as separate, high-resolution artwork files. These will be automatically incorporated into the single PDF that the system creates for review. For clarity and optimal reproduction please produce images near to the desired size of the printed version. The typesetting area of Polyhedron is 18.2 x 24cm; the width of a single column is 8.4 cm. Check that the resolution of all figures is high enough to be suitable for printing (300-1000 dpi). A detailed guide on electronic artwork is available on our website:
http://www.elsevier.com/artworkinstructions.
Colour illustrations. Authors may now submit colour pictures and other supplementary material along with their paper. If, together with the accepted article, usable colour figures are submitted 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 or not these illustrations are reproduced in colour in the printed version. 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. Alternatively, the publisher and author will each bear part of the extra costs involved.

References
References should be numbered consecutively throughout the text, and should be collected together in a reference list at the end of the paper. Journal abbreviations used should normally conform to the "Chemical Abstracts Service Source Index".
Indicate references in the text by number(s) in square brackets. The actual authors can be referred to, but the reference number(s) must always be given. Article and chapter titles are not needed.

Contact details for questions arising after acceptance of an article, especially those relating to proofs, are provided after registration of an article for publication.

Supplementary material
For Polyhedron, supplementary material usually takes the form of crystallographic data that has been deposited prior to submission. It is not necessary to submit files of this material with the manuscript if the procedures listed below have been followed. However, authors are recommended to submit any further information which they feel may aid the refereeing process, particularly if any of the usual quality-of-structure indicators point to problems in the analysis with the manuscript, as supplementary sheets. This should be clearly marked so that these files will not be published.
Should an author have supplementary material that they wish to publish online with their article, Elsevier accepts supplementary material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting applications, movies, animation sequences, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. In order to ensure that your submitted material is directly usable, please ensure that data is provided in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file. For more detailed instructions please visit our artwork instruction pages at http://www.elsevier.com/artworkinstructions.

Validation of Deposition of Crystallographic Data
Information and Instructions to Authors of Papers Containing or Comprising Crystal Structure Determinations

1. Policy
The Journal will accept for publication, papers containing, or comprising the results of crystal structure determinations which will be of interest to inorganic chemists. Papers reporting only crystallographic results must relate to work of novelty or special significance to inorganic and organometallic chemistry which must be emphasised.

2. Submission of Papers
The following procedures should be followed:

a) 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 the data corresponding to each structure to be reported in the intended publication with the relevant Date Centre Data for metal organic structures, i.e. those which contain organic carbon in any of the species present in the structure, (including metal carbonyls) should be sent to: The Cambridge Crystallographic Data Centre (CCDC), by e-mail (address: deposit@ccdc.cam.ac.uk), preferably in CIF format. A checklist of data items to be included in the deposition can be obtained from the CCDC home page ( http://www.ccdc.cam.ac.uk/), or by e-mail (fileserv@ccdc.cam.ac.uk), with the one line message: sendme checklist.

Data for inorganic compounds should be sent to: Fachinformationszentium Karlsruhe (FIZ), by e-mail (address: crysdata@FIZ-Karlsruhe.de), by FTP (please contact FIZ if you choose this option), or on disk. No hard copy submissions will be accepted.

Within a day or two of submission the Data Centres will provide deposition codes for each data set. This should be noted in the Supplementary Material section at the end of the text file before the reference list in the manuscript submitted to the journal. The deposited data will be accessed by the journal and checked as part of the refereeing process.

b) When the paper is submitted to the Journal, the following guidelines should be adhered to: The Title should contain reference to the presence in the paper of X-ray crystallographic results. The Abstract should not contain crystal data, but should include a concise statement of the main features of the structural results.
The Experimental results must be presented in a concise format.

In general, authors should not include a detailed text description of data collection, crystal structure solution and refinement, especially if these followed standard procedures and no difficulties were met. Reference to a previous paper containing a more detailed experimental description can be given if relevant. However, if any parts of the structure analysis were unusual, and affected the presentation and/or accuracy of the results, then these should be discussed. The following crystallographic data should be given, all contained in a paragraph (if one structure reported), or table (two or more structures).

(i) Colour, habit and size of crystals used, and behaviour of the compound under ambient conditions if not mentioned elsewhere in the paper.
(ii) Chemical Formula. This should correspond to the complete chemical unit encompassing crystallographic symmetry (e.g., a centrosymmetric dimer should be included in full form). The use of fractional coefficients (e.g. 0.5H2O), should be used, only, if the unit has partial occupancy of its site. Formulae should be presented in a way that molecules, ionic fragments, solvate molecules etc. are separately identified.
(iii) Unit cell parameters with esds and X-ray wavelength used.
(iv) Crystal system, space group and number of complete chemical units (see ii) per cell.
(v) Type of diffractometer used and method of data collection. Total number of data collected, excluding any intensity controls, number unique Rint value, number observed (with cut-off parameter), and completeness of data to suitable 2 or sin / limit, use or otherwise of absorption correction.
(vi) Final results. Give values of R, Rw (and their definitions) and number of parameters. Indicate form of refinement (F or F2) and treatment of hydrogens.

Note. Easily derived parameters should not be given unless required in discussion of other data (e.g. number of solvent molecules, etc).

Discussion of the Structure. This must include a clear, labelled diagram of the structure (molecule, complex ion or unit cell contents if the structure is polymeric), and a list of relevant geometry parameters - interatomic distances, interbond angles, torsion angles etc. Data for geometrically less important parts of the structure, such as ligand sub groups (phenyl rings, alkyl groups etc.), should not be given. Packing diagrams of crystal structures of "molecular" compounds should not be given unless there are chemically important intermolecular interactions.
