Bis(μ-biphenyl-2,2′-dicarboxylato)bis[aqua(4,4′-dimethyl-2,2′-bipyridine-κ2N,N′)copper(II)]

Abstract

The molecule of the title binuclear copper(II) complex, [Cu2(C14H8O4)2(C12H12N2)2(H2O)2], is bisected by a crystallographic twofold axis. Each CuII 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.
