Complexes cis-[PtR2(dmso)2] and cis-[PtRCl(dmso)2](dmso = dimethyl sulphoxide) are readily obtained from K2[PtCl4] and SnMe3R (R = aryl or Me) in dmso at 70–90 °C. Hydrogen-1 n.m.r. spectra show that the dmso ligands are bound through sulphur in solution and that the dmso ligand trans to R in cis-[PtRCl(dmso)2] undergoes dissociation and exchange at ambient temperature.
