[Ph3PhCH2P]+[PdCl3(DMSO)] - · DMSO (I), [Ph4P]+[PdCl 3(DMSO)]- (II), and [Ph4Sb(DMSO)] +[PdCl3(DMSO)]- (III) complexes have been synthesized via the reaction of palladium chloride with equimolar amounts of triphenylbenzylphosphonium chloride, tetraphenylphosphonium chloride, and tetraphenylstibonium chloride, respectively. According to X-ray diffraction data, the cations of complexes I (CPC = 104.90(8)° -111.61(9)°) and II (CPC = 105.12(10)°-111.46(10)°) have slightly distorted tetrahedral structures with P-C bond lengths of 1.786(2)-1.809(2) and 1.791(2)-1.799(2) Å, respectively. The antimony atom in the [Ph4Sb(DMSO)] + cation has a trigonal bipyramidal surrounding with the dimethyl sulfoxide (DMSO) oxygen atom in an axial position (Sb.O 2.567(2) Å). The palladium atoms in the square mononuclear anions of complexes I, II, and III are tetracoordinate, and Pd-Cl distances are 2.3101(5)-2.3104(5) Å, 2.2950(7)-2.2038(7) Å, and 2.2986(9)-2.3073(9) Å, respectively. The DMSO ligands are coordinated to the palladium atom through the sulfur atom (Pd-S, 2.2318(5) (I), 2.2383(6) (II), and 2.2410(9) Å (III)). © 2013 Pleiades Publishing, Ltd.
