Abstract
TheX-ray analysis of the title compound was based on 4 198 diffractometric intensity data, corrected for absorption, Crystals are triclinic. space group P, a= 10.4822(9), b= 9.5929(7), c= 11.0065(8)Å. α= 97.57(1). β= 117.96(1), γ= 93.80(1)°. Z= 2. The structure was solved by the heavy-atom method and refined by full-matrix least-squares to R 0.037. The crystals are built of discrete monomeric molecules with cis-square-planar geometry. The Pt–C [1.858(7)Å] and Pt–Cl(trans to C)[2.276(1)Å] distances indicate that the carbonyl ligand possesses π-acceptor properties and exerts an extremely small trans-influence on the Pt–Cl bond. The Pt–P [2.282(2)Å] and Pt–Cl(trans to P)[2.343(2)Å] bond lengths may reflect a weak cis-influence of the carbonyl group.Keywords
