metal-organic compounds
The Pt atom has a slightly distorted square-planar coordination in both title compounds, cis-[PtBr2(C2H6OS)2] and trans-[PtI2(C2H6OS)2], with the dimethyl sulfoxide ligands bonded via their S atoms. The bond distances to platinum in the bromo compound are Pt-Br 2.441 (1) and 2.447 (2), and Pt-S 2.254 (2) and 2.245 (2) Å, and in the centrosymmetric iodo complex are Pt-I 2.6111 (9) and Pt-S 2.289 (2) Å.
