The structure of the title compound, [CrCl2(C2H6OS)4]Cl·C2H6OS, consists of a CrIII ion coordinated by four O atoms of dimethyl sulfoxide (DMSO) ligands and two chloride ions in cis positions, forming a distorted CrCl2O4 octahedron. An isolated Cl- counter-anion and a positionally disordered DMSO molecule [occupancy ratio 0.654 (4):0.346 (4)] are also present. In the structure, the complex cations interact with the Cl- counter-anions and the DMSO solvent molecules via weak C-HCl and C-HO interactions, forming a three-dimensional network.
