trans-Bis(acetonitrile-N)tetraaquacobalt(II) tetrachloridocobaltate(II)

V. Patroniak and M. Kubicki

Abstract: In the title complex, [Co(CH₃CN)₂(H₂O)₄][CoCl₄], the Co^II ions are octahedrally coordinated in the cation, with trans-disposed acetonitrile ligands, and tetrahedrally coordinated in the anion. An extensive network of O-H(water)Cl hydrogen bonds between cations and anions connects the ions into a three-dimensional network. The Co-Cl distances correlate with the number of hydrogen bonds accepted by the Cl atoms.
