In the title compound, Pt(C(18)H(15)P)(C(28)H(28)P(2)S)(2*-)C(3)H(6)O or Pt(PPh(3))(PSP)(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.
在标题化合物Pt(C₁₈H₁₅P)(C₂₈H₂₈P₂S)₂⁻·C₃H₆O或Pt(PPh₃)(PSP)₂·CH₃COCH₃中，其中PSP是潜在的三齿螯合配体双(2 - 二苯基膦基乙基)硫化物，PSP配体的所有三个供体基团均与中心Pt原子配位，Pt—P = 2.310(1) Å且Pt—S = 2.343(1) Å。第四个配位点被三苯基膦配体的P供体占据[Pt—P = 2.289(1) Å]。配合物阳离子具有精确的镜像对称性，S原子、Pt原子和PPh₃配体的P原子位于镜像平面内。Pt原子具有扭曲的平面正方形配位几何构型。在PPh₃配体的苯环与PSP螯合物的末端 -PPh₂基团之间存在π - π相互作用。
