Polymeric bis[bis(2,2'-bipyridine)-nickel(II)] hexavanadate(V).
The structure of the title compound, mu-hexavanadato(V)-bis[bis(2,2'-bipyridine)nickel(II)], [(Ni(C(10)H(8)N(2))(2))(2)(V(6)O(17))], is composed of vanadium oxide layers intercalated by complex [Ni(bipy)(2)](2+) cations (bipy is 2,2'-bipyridine). The structure is isomorphous with that reported recently for [Zn(bipy)(2)](2)[V(6)O(17)] [Zhang, DeBord, O'Connor, Haushalter, Clearfield & Zubieta (1996). Angew. Chem. Int. Ed. Engl. 35, 989--991]. The vanadium oxide layers are built up solely from VO(4) tetrahedra by corner sharing and clearly exhibit a sinusoidal ruffling. Two O atoms from a single vanadium oxide layer are coordinated to each Ni atom of the complex cations in a cis fashion, with Ni--O distances of 2.027 (3) and 2.087 (3) A, thus maintaining the two-dimensional structure.
