The reaction of tetraphenylphosphonium chloride with an equimolar amount of potassium tetrachloroplatinate or hexachloroplatinic acid in dimethyl sulfoxide gave the complexes [Ph4P]+[PtCl3(DMSO)] - (I) and [Ph4P]+[PtCl5(DMSO)] - (II), respectively. The phosphorus atoms in the cations have tetrahedral environment, the CPC angles and P-C distances 105.63(13) -112.13(14), 1.795(3)-1.797(3) Å I) and 105.7(3) -112.9(3), 1.783(7)-1.791(6) Å II). The platinum coordination polyhedra in the anions [PtCl3(DMSO)]- and [PtCl5(DMSO)]- are distorted square (Pt-S, 2.1937(8); Pt-Cl, 2.2894(10)-2.3024(10) Å; trans-angles: SPtCl, 177.38(4); ClPtCl, 175.40(4)) and octahedron (Pt-S 2.291(2) Å; Pt-Cl, 2.312(2)-2.334(2) Å, trans-angles: SPtCl, 178.28(9); ClPtCl, 178.80(9) and 178.88(8)). © 2013 Pleiades Publishing, Ltd.
