Abstract
The structure of trans-ptCl(CH2CN)(PPh3)2 has been determined from three dimensional X-ray data. The complex crystallizes in the monoclinic system, space group C52h-P21/n with four molecules in a unit cell of dimension, a = 12.366(5), b = 23.019(8), c = 12.303(4) Å, β = 110.7(1)°. Least-squares refinement of 137 variables has led to a value of the conventional R index (on F) of 0.038 for the 4313 independent reflections having I ≥ 3σ(1). The complex is a typical square-planar Pt(II) complex; structural parameters: PtP, 2.308(3) and 2.310(3), PtCl, 2.390(3), PtC(1), 2.08(1), C(1)C(2), C(2)N(1), 1.15(2) Å; PtC(1)C(2), 111.1(8)° andC(1)C(2)N(1), 180.0(8)°. The crystal packing is determined only by van der Waals interaction and all intermolecular contacts agree with those predicted from radiisum rules. © 1979.
