Tris(2,2′-bipyridine-κ(2) N,N′)cobalt(III) octa­cyanido­tungstate(V)

In the title compound, [Co(C(10)H(8)N(2))(3)][W(CN)(8)], the Co atom (..2 site symmetry) is coordinated by six N atoms from three 2,2′-bipyridine ligands in an octa­hedral geometry; the Co—N bond distances range from 1.926 (2) to 1.939 (2) Å. The W (..2 site symmetry) metal center is coordinated by eight cyanide ligands, resulting in a dodeca­hedral conformation with W—C distances in the range 1.165 (3)–2.176 (3) Å. The cations and anions are linked into a three-demensional structure by weak C—H⋯N hydrogen bonds.
