Crystal and molecular structure of fumaronitrilebis(triphenylphosphine)-platinum

Abstract

The structure of fumaronitrilebis(triphenylphosphine)platinum has been determined from three-dimensional single-crystal X-ray diffraction data. The compound crystallizes in the monoclinic space group, P2₁/c, with a= 9·146, b= 17·568, c= 21·551 Å, and β= 101° 23′. The structure has been solved by three-dimensional Fourier synthesis with 3775 observed structure factors and refined by full-matrix least-squares methods to a final R of 8·3%. The olefinic carbon–carbon distance is essentially a single-bond value. The two independent platinum–carbon distances (2·05 and 2·16 Å) are apparently not equivalent. The dihedral angle between the planes P(1), Pt, P(2) and C(1), Pt, C(2) is 5·2°.
