Di-aqua-tetra-kis-(di-methyl sulfoxide-κO)cobalt(II) bis--[diammine-tetra-kis-(thio-cyanato-κN)chromate(III)] di-methyl sulfoxide hexa-solvate dihydrate

摘要

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 mol-ecules (six DMSO and two water). The crystal packing consists of a branched three-dimensional system of hydrogen bonds involving the DMSO and water solvent mol-ecules, the S atoms of the thio-cyanate ligands, and the coordinating NH3?and H2O mol-ecules.
