Reaction of the complex [PtCl{P(O)Ph2}{P(OH)Ph2}2] with silver or thallium derivatives of dithiolate ligands led to neutral complexes of general formula [Pt{S – S}{P(O)Ph2}{P(OH)Ph2}], where {S – S}- = {S2CNEt2}- (1), {S2P(OEt)2}- (2) and [S2COEt]- (3). Complexes 2 and 3 reacted with an excess of NaI in acetone solution by dealkylation of the coordinated dithiolate ligand and formation of the compounds [Pt{S2P(O)(OEt)}{P(O)Ph2}{P(OH)Ph2}]Na (4) and [Pt{S2CO}{P(O)Ph2}{P(OH)Ph2}] Na (5), respectively. The corresponding tetraphenylphosphonium derivatives (6, 7) were prepared by a metathetical reaction of these complexes with Ph4PBr in acetone solution. Related dithiolate complexes were obtained by reaction of the complex [Pt{S – S}2] with P(OMe)Ph2 in molar ratio 1 : 2. Thus, the reaction of [Pt{S2COEt}2] in dichloromethane solution at room temperature gave [Pt{S2COEt}{P(OMe)Ph2}2]Cl (8). This complex reacted with NaI in acetone to form the neutral compound [Pt{S2CO}{P(OMe)Ph2}2] (9). When the reaction was carried out in dichloromethane at reflux temperature using [Pt{S2P(OEt)2}2] as starting material, the neutral compound [Pt{S2P(O)(OEt)} {P(OMe)Ph2}2] (10) was obtained. The crystal structure of the complex 9 has been determined by X-ray diffraction. The neutral complex shows a nearly square-planar coordination of the metal and a planar dithiocarbonate ligand.
