metal-organic compounds
The title complex, [Cu2(C2O4)(C12H8N2)2(H2O)2](NO3)2·2H2O, is a centrosymmetric oxalate-bridged binuclear CuII 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.
organic compounds
The organic moiety of the title compound, C11H18NO5P·2H2O, is zwitterionic. The crystal packing is stabilized by N—HO and O—HO hydrogen bonds.
