Oxidation of transition metals in the liquid phase. 9. Direct synthesis and X-ray structural examination of complexes [(Me2S)AuBr] and [(Me2S)AuBr3

Abstract

Oxidation of Au0 in the DMSO-HBr system has given dimethyl sulfide complexes of mono-and trivalent gold, [(Me2S)AuBr] and [(Me2S)AuBr3]. X-ray diffraction examination has shown that in the crystal of the first complex there are chain intermolecular contacts Au...Au (3.22 a), and in the crystal of the second, intermolecular Au...Br contacts which extend the square planar coordination of the gold atoms to distorted bipyramidal.
