In the title organic-inorganic hybrid vanadate complex, [Cu(2)V(6)O(17)(C(10)H(8)N(2))(4)](n), the Cu(II) atom is six-coordinated by two chelating 2,2'-bipyridine (bipy) ligands and two vanadate O atoms in a distorted octa-hedral geometry. Two [Cu(bipy)(2)V(3)O(8)] units are linked by a bridging O atom, which lies on an inversion center, forming a dimeric unit. The dimeric units are further connected by bridging vanadate O atoms into a two-dimensional layer parallel to (100). The layers are connected by weak C-H⋯O hydrogen bonds.
