Tetrachloroaurate(/II) 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] I-BPh4] (I). The X-ray crystal structure of the complex shows it has a square planar geometry. Kz[PtCI J or PtC12 react with DPPBTH in mildly alkaline MeOH to give the 16 electron platinum(II) complex [Pt(DPPBT)2] (2), whilst reaction of Na 2 [PdC14] with DPPBTH under similar conditions gives the 16 electron palladium complex [Pd(DPPBT)z ] (3). The complexes have been studied by u.v., i.r. and n.m.r. The electrochemical behaviour of complex (I) was also investigated.
