Abstract

Addition of 1 equiv. (Ph3P)Au(ClO4) (formed by ion exchange of Ph3PAuCl with AgClO4) to [naphthalene-1,8-bis(thiolato)]bis (triphenylphosphane) platinum results in the formation of a novel dimetallic cationic complex with a (triphenylphosphane)gold moiety attached to the sulfur of the naphthalene-1,8-bis(thiolato) ligand. NMR spectroscopic evidence suggests that this gold-containing fragment is fluxional in its bonding and X-ray crystallography confirms the asymmetric complex, which shows this gold atom attached to one of these sulfur atoms. Addition of more than 1 equiv. (Ph3P)Au-(ClO4) results in the formation of a tetrametallic sandwich complex with two bridging gold atoms between the sulfur atoms of the two PtS2C3 rings. Tri- and tetrametallic silver-containing complexes can be prepared by addition of 0.5 and 1 equiv. AgClO4 to (Ph3P)(2)Pt(S2C10H6), respectively. (c) Wiley-VCH Verlag GmbH & Co.
