STRUCTURE OF BIS(THIOUREA)GOLD(I) BROMIDE, [AU(SC(NH2)2)2]BR

[Au(CH4N2S)2]Br, M(r) = 429.20, monoclinic, C2/c, a = 8.703 (2), b = 16.025 (8), c = 6.799 (2) angstrom, beta = 100. 83 (2)-degrees, V = 931.3 (6) angstrom3, Z = 4, D(x) = 3.060 Mg m-3, lambda(Mo Kalpha) = 0.71073 angstrom, mu = 20.394 mm -1, F(000) = 776, T = 298 K, R = 0.0632 and wR = 0.0929, obtained for 48 variable parameters and 609 averaged reflections with F > 0sigma(F). The asymmetric unit consists of one half of a centrosymmetric bis(thiourea)gold(I) molecule with thiourea ligands coordinating in a monodentate fashion through the S atom [Au(l)-S(1) = 2.291 (4) angstrom]. The thiourea groups are essentially planar but are twisted by an angle of 21.0-degrees about the S-C atoms. The Au atoms in adjacent molecules are separated by a distance of 3.400 angstrom and the Br- counterions are located in the cavities formed by the terminal amine groups of the thiourea ligands.
