cis-Dichloridotetrakis(dimethyl sulfoxide-κO)chromium(III) chloride dimethyl sulfoxide monosolvate

Abstract

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—H...Cl and C—H...O interactions, forming a three-dimensional network.
