Diaquatetrakis(dimethyl sulfoxide-κO)cobalt(II) bis[diamminetetrakis(thiocyanato-κN)chromate(III)] dimethyl sulfoxide hexasolvate dihydrate

Abstract

The solvated title salt, [Co(C2H6OS)4(H2O)2][Cr(NCS)4(NH3)2]·6C2H6OS·2H2O, is build up from a complex [Co(DMSO)4(H2O)2]2+ cation (where DMSO is dimethyl sulfoxide), two Reinecke's Salt anions, i.e. [Cr(NCS)4(NH3)2]−, as the complex counter-ions, together with solvent molecules (six DMSO and two water). The crystal packing consists of a branched three-dimensional system of hydrogen bonds involving the DMSO and water solvent molecules, the S atoms of the thiocyanate ligands, and the coordinating NH3 and H2O molecules.
