Abstract:
The structure of the title compound, [CrCl2(C2H6OS)4]Cl·C2H6OS, 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 CrCl2O4 octa-hedron. An isolated Cl(-) counter-anion and a positionally disordered DMSO mol-ecule [occupancy ratio 0.654 (4):0.346 (4)] are also present. In the structure, the complex cations inter-act with the Cl(-) counter-anions and the DMSO solvent mol-ecules via weak C-H⋯Cl and C-H⋯O inter-actions, forming a three-dimensional network.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
