Mononuclear complexes of formula (M = Pd 1 or Pt 2; R = C5H9NMe, dppe = Ph2PCH2CH2PPh2) are formed in reactions of with the sodium salt of 4-mercapto-1-methylpiperidine NaSR in acetonitrile-methanol solution.Subsequent reaction of 1 with and of 2 with in acetonitrile solution produces the bridged dinuclear cationic complexes (2+), which are obtained as crystalline salts with tetraphenylborate anions (M = Pd 3 or Pt 4).An apparently mixed PtPd product 5 is formed in an analogous reaction from 1 and or from 2 and .The structures of complexes 1-5 have been determined crystallographically.Complexes 1 and 2 are isostructural, with a slightly distorted square-planar cis-MP2S2 co-ordination geometry.The isostructural complexes 3-5 also show square-planar co-ordination; the two aminothiolate ligands act as bridges between the metal atoms, giving a precisely planar central M2S2 ring.In all five structures the MP2C2 chelate rings have a twist conformation.The nitrogen atoms of the aminothiolates are not co-ordinated to the metal atoms.Infrared and (1)H, (31)P and (195)Pt NMR spectra are presented and discussed.The combined evidence suggests that 5 is essentially a simple solid-solution mixture of pure complexes 3 and 4 in variable proportions, with at most a minor component of a genuinely heterobimetallic complex.
