Abstract
The title compound, cis-hydrido(triphenylsilyl)-1,4-butanediyl-bis-(diphenylphosphine)platinum(II) (I), crystallizes in the monoclinic space groupP2 1/n (No. 14) witha=9.472(4),b=16.924(5),c=25.799(4) Å, β=91.29(3)° andZ=4. The structure was solved using the direct methods and refined by the full-matrix least-squares procedure to yield residuals ofR=0.024 andR w =0.025 based on 4160 unique reflections. The square-planar geometry about the Pt atom is angularly distorted with P(1)−Pt−P(2) and Si−Pt−P(2) angles of 103.5(1) and 102.1(1)°, respectively. The Pt−P(1) bond is longer than the Pt−P(2) bond due to thetrans influence of the SiPh3 group. Distortion due to steric bulk of the ligands is accommodated by the opening of the tetrahedral angles at the silicon and phosphorous atoms.
