Abstract: The title compound, [Cu₂(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) Å] and one longer Cu-O contact [2.4338 (17) and 2.5541 (17) Å] 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.
