The platinum(II) thiosalicylate complex [Pt(SC6H4CO2)(PPh3)2] 1a reacts with HgI2 to form a tetrametallic complex comprising an IHg(μ-I)2HgI central core with the thiolate sulphur of 1a coordinated to each mercury centre, completing a distorted tetrahedral coordination environment. Overall, the structural features of the complex, determined by an X-ray diffraction study, are similar to the parent thiosalicylate complex 1a, but with an increased fold angle (59° compared to 46°) of the thiosalicylate ligand relative to the platinum coordination plane. Reactions of related five-membered ring thiolate complexes [Pt(SCHRCO2)(PPh3)2] (R=H or Me) and of 1a with a range of metal cations were investigated using 31P NMR spectroscopy. Changes in the 1J(PtP) coupling constants are discussed in terms of coordination to the various metal halide moieties. Reactions of the organomercury(II) thiosalicylate complex Thiomersal (EtHgSC6H4CO2Na) with cis-[PtCl2(PPh3)2], or cis-[MCl2(dppe)] (M=Ni or Pd) leads to complete transfer of the thiosalicylate ligand from the mercury, and isolation of the previously reported thiosalicylate complexes [Pt(SC6H4CO2)(PPh3)2] and [M(SC6H4CO2) (dppe)] (M=Ni, Pd) in high yields.
