In the title compound, [PtCl₂(C₂₁H₂₁O₃P)₂]·2C₃H₆O, the asymmetric unit contains a Pt^II ion situated on an inversion center, one chloride anion, one tris(4-methoxylphenyl)phosphane (L) ligand and one acetone solvent molecule. The Pt^II ion is coordinated by two P atoms [Pt-P = 2.3196 (5) Å] from two L ligands and two chloride anions [Pt-Cl = 2.3075 (5) Å] in a distorted square-planar geometry with P-Pt-Cl angles of 88.016 (16) and 91.984 (16)°. The effective cone angle of the phosphane ligand was calculated to be 156°. Weak C-HO and C-HCl hydrogen bonds hold molecules together.
