Compounds containing platinum–carbon bonds. Part V. Crystal and molecular structure of a carbenoid complex of platinum(IV), [PtCl2-{C(Cl·C6H3NH)(NHMe)}(PEt3)2]ClO4

Abstract

The molecular structure of the title complex has been determined by single-crystal X-ray analysis. Crystals are monoclinic, space group P2₁/a, a= 13·451 (2), b= 21. 381 (5), c= 13·368(2)Å, β= 130·73(1)°, Z= 4. The structure was solved by the heavy-atom method and refined by full-matrix least-squares to R 0·048 for 3811 diffractometric intensity data corrected for absorption.

In each complex cation mutually cis chlorine atoms, trans-phosphorus atoms, and cis-carbenoid and -phenyl carbon atoms define an octahedron about the platinum atom. The metal–ligand distances are: Pt–P 2·388(4), Pt–C(Ph) 2·034(11), Pt–C(carbenoid) 1·973(11), Pt–Cl 2·415(4)trans to phenyl, and 2·372(3)Åtrans to carbenoid.
