Tris(3,4,7,8-tetra­methyl-1,10-phenanthrolin-1-ium) hexa­cyanidocobaltate(III) penta­hydrate

The structure of the title compound, (C(16)H(17)N(2))(3)[Co(CN)(6)]·5H(2)O, consists of three 3,4,7,8-tetra­methyl-1,10-phenanthrolin-1-ium cations, a [Co(CN)(6)](3−) anion and five water mol­ecules of crystallization, one of which is disordered over two sets of sites in a 0.587 (15):0.413 (15) ratio. The [Co(CN)(6)](3−) anion exhibits an octa­hedral geometry. In the structure, cations and anions are linked alternatively through O—H⋯O, O—H⋯N, N—H⋯O and N—H⋯N hydrogen bonds, π–π inter­actions [centroid–centroid distances = 3.523 (2)–4.099 (2) Å] and van der Waals forces, forming a three-dimensional supra­molecular network.
