Reactions of triphenylbenzylphosphonium and tetraphenylstibonium chlorides with potassium tetrachloroplatinates in dimethylsulfoxide

Platinum complexes [Ph3PhCH2P]+[(Me 2S=O)PtCl3]- I and cis-Cl2(Ph 3Sb)(Me2S=O)Pt II were synthesized by reaction of triphenylbenzylphosphonium and tetraphenylstibonium chlorides with potassium tetrachloroplatinate in DMSO. Crystal I is formed by triphenylbenzylphosphonium tetrahedral cations [P-CPh 1.791(4)-1.795(4) A, P-C Alk 1.811(4) A; CPC 107.57(18)°-111.46(17)°] and by square anions [(Me2S=O)PtCl3]- [Pt-Cl 2.3236(11), 2.2981(12), 2.2977(11) A; Pt-S 2.1950(10) A; trans-angles SPtCl 177.51(4)°, ClPtCl 178.74(4)°]. In a square-planar complex II [trans-angles SPtCl 178.01(6)°, ClPtSb 177.96(4)°] with central platinum atom the chlorine atoms [Pt-Cl 2.308(1), 2.350(1) A], triphenylstibine [Pt-Sb 2.5118(4) A] and dimethyl sulfoxide [Pt-S 2.195(1) A] molecules are coordinated. Compound II is a first example of mixed ligand complex of platinum(II), where in the coordination sphere of central atom the tertiary stibine is present along with DMSO ligand.
