Abstract: The title compound, [Cu₂V₄O₁₂(C₁₀H₈N₂)₂]_n, shows a two-dimensional copper-vanadate layer composed of eight-membered rings, each containing four corner-sharing VO₄ 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 VO₄ units to form a distorted tetragonal pyramid. These layers are further connected by - 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.
