title: [Bis(2-diphenylphosphinoethyl) sulfide-kappa(3)P,S,P'](triphenylphosphine-kappa P)platinum(II) diperchlorate acetone solvate.
abstract: In the title compound, [Pt(C(18)H(15)P)(C(28)H(28)P(2)S)](ClO(4))(2*-)C(3)H(6)O or [Pt(PPh(3))(PSP)](ClO(4))(2*) x CH(3)COCH(3), where PSP is the potentially tridentate chelate ligand bis(2-diphenylphosphinoethyl) sulfide, all three donor groups of the PSP ligand are coordinated to the central Pt atom, with Pt[bond]P = 2.310 (1) A and Pt[bond]S = 2.343 (1) A. The fourth coordination site is occupied by the P donor of the triphenylphosphine ligand [Pt[bond]P = 2.289 (1) A]. The complex cation has exact mirror symmetry, with the S atom, the Pt atom and the P atom of the PPh(3) ligand in the mirror plane. The Pt atom has a distorted square-planar coordination geometry. A pi[bond]pi interaction is present between the phenyl rings of the PPh(3) ligand and the terminal -PPh(2) group of the PSP chelate.
