Poly[bis­(2,2′-bipyridine-κ(2) N,N′)deca-μ-oxido-dioxidodicopper(II)tetra­vanadium(V)]

The title compound, [Cu(2)V(4)O(12)(C(10)H(8)N(2))(2)](n), shows a two-dimensional copper–vanadate layer composed of eight-membered rings, each containing four corner-sharing VO(4) tetra­hedra; these are linked through six penta­coordinated Cu(II) atoms with the 2,2′-bipyridine ligands attached and pointing above and below the plane of the layer. The Cu atom is coordinated by two N donors from the 2,2′-bipyridine ligand and three O atoms from three adjacent VO(4) units to form a distorted tetragonal pyramid. These layers are further connected by π–π inter­actions between inter­leaving bipyridine ligands of adjacent layers [centroid–centroid distances = 3.63 (1) and 3.68 (1) Å] into a three-dimensional supra­molecular structure.
