title: trans-Bis(acetonitrile-κN)tetra-aqua-cobalt(II) tetra-chloridocobaltate(II).
abstract: In the title complex, [Co(CH(3)CN)(2)(H(2)O)(4)][CoCl(4)], the Co(II) ions are octa-hedrally coordinated in the cation, with trans-disposed acetonitrile ligands, and tetra-hedrally 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.
