Description:
The title complex, bis[μ3-cis-N-(2-aminopropyl)-N′-(2-carboxylatophenyl)oxamidato(3−)]-1:2:4κ7N,N′,N′′,O:O′,O′′:O′′′;2:3:4κ7O′′′:N,N′,N′′,O:O′,O′′-bis(2,2′-bipyridine)-2κ2N,N′;4κ2N,N′-dichlorido-1κCl,3κCl-tetracopper(II) dihydrate, [Cu4(C12H12N3O4)2Cl2(C10H8N2)2]·2H2O, consists of a neutral cyclic tetracopper(II) system having an embedded centre of inversion and two solvent water molecules. The coordination of each CuIIatom is square-pyramidal. The separations of CuIIatoms bridged bycis-N-(2-aminopropyl)-N′-(2-carboxylatophenyl)oxamidate(3−) and carboxyl groups are 5.2096 (4) and 5.1961 (5) Å, respectively. A three-dimensional supramolecular structure involving hydrogen bonding and aromatic stacking is observed.
