Abstract

Tetrachloroaurate(III) reacts with two equivalents of the bidentate (1-) mixed phosphinothiol ligand 2-(diphenylphosphino)benzenethiol (DPPBTH) in mildly alkaline MeOH to give a cation that can be precipitated from solution as the tetraphenylborate salt, the title complex [Au(DPPBT)₂][BPh₄] (1). The X-ray crystal structure of the complex shows it has a square planar geometry. K₂[PtCl₄] or PtCl₄ react with DPPBTH in mildly alkaline MeOH to give the 16 electron platinum(II) complex [Pt(DPPBT)₂] (2), whilst reaction of Na₂[PdCl₄] with DPPBTH under similar conditions gives the 16 electron palladium complex [Pd(DPPBT)₂] (3). The complexes have been studied by u.v., i.r. and n.m.r. The electrochemical behaviour of complex (1) was also investigated.
