trans-Dichloro(dimethyl sulfide-κS)(pyridine-κN)platinum(II)

The structure of the title compound, [PtCl(2)(C(5)H(5)N)(C(2)H(6)S)], consists of discrete molecules in which the Pt-atom coordination is slightly distorted square planar. The Cl atoms are trans to each other, with a Cl-Pt-Cl angle of 176.60 (7) degrees. The pyridine ligand is rotated 64.5 (2) degrees from the Pt square plane and one of the Pt-Cl bonds essentially bisects the C-S-C angle of the dimethyl sulfide ligand. In the crystal structure, there are extensive weak C-H...Cl interactions, the shortest of which connects molecules into centrosymmetric dimers. A comparison of the structural trans influence on Pt-S and Pt-N distances for PtS(CH(3))(2) and Pt(pyridine) fragments, respectively, in square-planar Pt(II) complexes is presented.
