Abstract

The title compound, [Au(C7H7S)(C18H15P)], is conformationally chiral and crystallizes from benzene-hexane as individually enantiopure crystals. This mononuclear compound has the Au(I) atom linearly bound to a triphenylphosphine P atom and to a phenyl C atom of a 2-(methylsulfanyl)phenyl group. The angle at the Au(I) atom is 175.9 (2) degrees. The linear ligand coordination about the Au(I) atom has geometric parameters inside the remarkably narrow range found for gold complexes bound by a phosphine ligand and by the ortho-C atom of a substituted phenyl group. This is the first example of gold(I) attached to a methylsulfanyl aromatic carbanion.
