Notes: Abstract The reaction ofcis-[PtCl2(CO)(PPh3)] with two equivalents of SnCl2. 2H2O in acetone solution allows isolation ofcis-[PtCl2(PPh3)2] as the acetone solvate, the crystal structure of which has been determined. Crystals ofcis-[PtCl2(PPh3)2]·C3H6O are monoclinic, space groupP21/c (No. 14) with four formula units in a cell of dimensionsa=10.288(3),b=24.372(5),c= 15.367(3) Å, /gb=98.07(2)°. The structure was solved by the heavy-atom method and refined by full-matrix least-squares calculations to a finalRof 0.033 for 3761 reflections withI〉(I). The crystal structure contains discrete well-resolvedcis-PtCl2(PPh3)2 molecules with acetone of solvation filling cavities in the crystal structure. The Pt coordination is slightly distorted square-planar with Pt-Cl 2.333(2) and 2.356(2), Pt-P 2.251(2) and 2.265(2) Å, P-Pt-P 97.8(1), and Cl-Pt-Cl 87.1(1)°.
