Bis(μ-biphenyl-2,2′-dicarboxylato)bis[(2,2′-bipyridine)copper(II)]

The title compound, [Cu-2(C14H8O4)(2)(C10H8N2)(2)], was obtained by solvothermal synthesis. The Cu-II atom is coordinated by one chelating 2,2'-bipyridine ligand and two carboxyl groups from different biphenyl-2,2'-dicarboxylate ligands, leading to a distorted octahedral environment. Each carboxylate group makes one short Cu-O bond [1.9608 (14) and 1.9701 (14) angstrom] and one longer Cu-O contact [2.4338 (17) and 2.5541 (17) angstrom] to each Cu-II atom. The biphenyl-2,2'-dicarboxylate ligands bridge between Cu-II atoms, forming a dinuclear complex around a crystallographic inversion centre.
