Abstract

The crystal and molecular structure of tetracyanoethylenebis(triphenylphosphine)platinum(0) has been determined from three-dimensional X-ray diffraction data collected by film methods. The substance crystallizes in the monoclinic space group P21/c with Z= 4 in a unit cell of dimensions a= 17·51 (3), b= 11·23(2), c= 18·52(4)Å, and β= 97° 10′(10′). Least-squares refinement of the structure gave R 0·088 for 2242 observed reflections. The structure consists of well separated monomeric units, in which the platinum atom exhibits a distorted square-planar co-ordination geometry with the two phosphorus and two carbon atoms of the tetracyanoethylene moiety in the cis-configuration. The C[double bond, length half m-dash]C bond-distance of 1·49 Å is 0·18 Å greater than the corresponding distance in the free ligand.
