|Section2= |Section7= }} Gold(III) bromide is a dark-red to black crystalline solid.〔Macintyre, J. E. (ed.) ''Dictionary of Inorganic Compounds''; Chapman & Hall: London, 1992; vol. 1, pp. 121〕〔Greenwood, N.N.; Earnshaw, A. ''Chemistry of the Elements''; Butterworth-Heineman: Oxford,1997; pp. 1183-1185〕〔Cotton, F.A.; Wilkinson, G.; Murillo, C.A.; Bochmann, M. ''Advanced Inorganic Chemistry''; John Wiley & Sons: New York, 1999; pp. 1101-1102〕 It has the empirical formula AuBr3, but exists primarily as a dimer with the molecular formula Au2Br6 in which two gold atoms are bridged by two bromine atoms.〔〔〔Schulz, A.; Hargittai, M. ''Chem. Eur. J.'' 2001, vol. 7, pp. 3657-3670〕 It is commonly referred to as gold(III) bromide, gold tribromide, and rarely but traditionally auric bromide, and sometimes as digold hexabromide. As is similar with the other gold halides, this compound is unique for being a coordination complex of a group 11 transition metal that is stable in an oxidation state of three whereas copper or silver complexes persist in oxidation states of one or two.〔Schwerdtfeger, P.'' J. Am. Chem. Soc.'' 1989, vol. 111, pp. 7261-7262〕 ==History== The first mention of any research or study of the gold halides dates back to the early-to-mid-19th century, and there are three primary researchers associated with the extensive investigation of this particular area of chemistry: Thomsen, Schottländer, and Krüss.〔Lengefield, F. ''American Chemical Journal'' 1901, vol. 26, pp. 324〕〔Thomsen, J.'' J. prakt. Chem.'' 1876, vol. 13, pp. 337〕〔 Schottländer, ''Ann. Chem. (Liebig)'', vol. 217, pp. 312〕〔Krüss, G. ''Ber. d. chem. Ges.'' 1887, vol. 20, pp. 2634〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gold(III) bromide」の詳細全文を読む スポンサード リンク
