- Abstract
Organyltriphenylphosphonium and -stibonium hexabromoplatinates were synthesized by the reaction of potassium hexabromoplatinate with organyltriphenylphosphonium and -stibonium bromides in acetonitrile or water. The complexes [Ph3PC2H5]2[PtBr6] and [Ph3PCH2Ph]2[PtBr6] were obtained by recrystallization from dimethyl sulfoxide; the complexes [Ph3PCH2Ph][PtBr5(Et2SO-S)] and [Ph4Sb·Et2SO-O]2[PtBr6], by recrystallization of benzyltriphenylphosphonium and tetraphenylstibonium hexabromoplatinates from diethyl sulfoxide. According to the X-ray data, phosphorus atoms in cations have a distorted tetrahedral coordination and antimony atoms, a distorted trigonal-bipyramidal coordination due caused by the Sb···O=SEt2 interaction.
