cis‐Dichloridobis(diethyl sulfide‐κS)platinum(II) at 295 and 150 K

The title compound, cis‐[PtCl₂(C₄H₁₀S)₂], crystallizes in the space group P2₁/n with pseudo‐square‐planar coordination geometry. The orientation of the ethyl groups on the S atoms is staggered with respect to the coordination plane, giving the complex approximate C_2v symmetry. The complex does not form dimeric packing units with short Pt...S intradimeric distances as seen in some related complexes, but instead displays C—H...Cl interactions in three dimensions. These C—H...Cl—Pt contacts are compared with those of related compounds reported in the Cambridge Structural Database, which show a frequency maximum in the range 120–170° for the C—H...Cl angle.
