Bis(μ-biphenyl-2,2′-dicarboxyl­ato)bis­[aqua­(4,4′-dimethyl-2,2′-bipyridine-κ(2) N,N′)copper(II)]

The mol­ecule of the title binuclear copper(II) complex, [Cu(2)(C(14)H(8)O(4))(2)(C(12)H(12)N(2))(2)(H(2)O)(2)], is bis­ected by a crystallographic twofold axis. Each Cu(II) atom is coordinated in a distorted octa­hedral geometry by three O atoms from two biphen­yl-2,2′-dicarboxyl­ate anions, one aqua O atom and two N atoms of a 4,4′-dimethyl-2,2′-bipyridine ligand. Intramolecular O—H⋯O hydrogen bonds between the coordinated water molecules and the carboxylate O atoms are also present.
