Halogen Chemistry, Volume 3 focuses on advancement in the study of halogens. Composed of contributions of authors, the book focuses on discussions on halides that contain multicentred metal-metal bonds. The discussions are initialized with an introduction; identification of factors that influence metal-metal bond formation; and compounds that contain multi-centred metal-metal bonds. The text also looks at the nature of metal-halogen bonds and the metal-halogen vibrational frequencies. Numerical representations and tabulations are presented as well. The book also looks at the halides of niobium and tantalum. Concerns include fluorine, chlorine, bromine, and iodine compounds. The compilation further considers pentahalides of transition metals and halide chemistry of chromium, molybdenum, and tungsten. The book closes with discussions on halogen chemistry of actinides and halogeno metal carbonyls and related compounds. Covered areas include trivalent, tetravalent, pentavalent, and hexavalent actinides, and structures and reactions of halogeno metal carbonyls. The compilation is a valuable source of information for readers interested in the study of halogens.
