Abstract: The title complex, [Cu₂(C₂O₄)(C₁₂H₈N₂)₂(H₂O)₂](NO₃)₂·2H₂O, is a centrosymmetric oxalate-bridged binuclear Cu^II complex with an inversion center located at the mid-point of the C-C bond of the bridging oxalate ligand. The Cu atom has five-coordinate square-pyramidal geometry. A network of O-HO hydrogen bonds helps to consolidate the crystal packing.
