Abstract: | In the title compound, Pt(C18H15P)(C28H28P2S)](ClO4)2·C3H6O or Pt(PPh3)(PSP)](ClO4)2·CH3COCH3, 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—P = 2.310 (1) Å and Pt—S = 2.343 (1) Å. The fourth coordination site is occupied by the P donor of the triphenylphosphine ligand Pt—P = 2.289 (1) Å]. The complex cation has exact mirror symmetry, with the S atom, the Pt atom and the P atom of the PPh3 ligand in the mirror plane. The Pt atom has a distorted square‐planar coordination geometry. A π–π interaction is present between the phenyl rings of the PPh3 ligand and the terminal –PPh2 group of the PSP chelate. |
