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

Abstract

Key indicators: single-crystal X-ray study; T = 150 K; mean (S-C) = 0.005 Å; disorder in solvent or counterion; R factor = 0.051; wR factor = 0.138; data-toparameter ratio = 22.6.The structure of the title compound, [CrCl 2 (C 2 H 6 OS) 4 ]ClÁ-C 2 H 6 OS, consists of a Cr III ion coordinated by four O atoms of dimethyl sulfoxide (DMSO) ligands and two chloride ions in cis positions, forming a distorted CrCl 2 O 4 octahedron. An isolated Cl À 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 À counter-anions and the DMSO solvent molecules via weak C-HÁ Á ÁCl and C-HÁ Á ÁO interactions, forming a threedimensional network.
