The structure of the title compound, [SnCl₂(CH₃)₂(C₈H₁₈O₂S₂)]_n has been determined and revealed the occurrence of infinite chains of tin complexes bridged by disulfoxide derivatives. The Sn^IV atom is hexacoordinate in a distorted octahedral environment, with Cl atoms at distances of 2.521 (1) and 2.515 (1) Å, and methyl carbanions at distances of 2.110 (4) and 2.111 (4) Å. Two different disulfoxide groups, with Sn-O distances of 2.316 (3) and 2.320 (3) Å, complete the coordination. NMR spectroscopy indicated the occurrence of discrete binuclear molecules in solution.
