trans-dichlorobis(di-n-propyl sulfoxide)platinum(II)

[PtCl2(C6H14OS)2], Mr = 534.48, monoclinic, P2(1)/c, a = 9.092 (2), b = 5.696 (2), c = 19.749 (7) A, beta = 110.63 (3) degrees, V = 957.2 (6) A3, Z = 2, D chi = 1.854 Mg m-3, lambda(Mo K alpha) = 0.71069 A, mu(Mo K alpha) = 7.894 mm-1, F(000) = 520, room temperature, R = 0.047 for 1842 unique observed reflections. The Pt atom is located on a center of symmetry. Pt has trans square-planar coordination and the sulfoxide ligands are bonded through their S atoms. The Pt-Cl bond distances are 2.292 (3) A. The Pt-S bond lengths [2.292 (2) A] are significantly longer than the corresponding distances in the cis isomer. The packing consists of layers of molecules parallel to the ab plane.
