Abstract: Each Cu atom in the centrosymmetric dinuclear title compound, [Cu2(C3H5O5P)2(C12H8N2)2(H2O)2], is chelated by an N-heterocycle and is also coordinated by a molecule of water. The two Cu atoms are bridged by the 3-phosphonopropionate(2-) unit, giving rise to a square-pyramidal geometry for the metal centre. The molecules are linked by hydrogen bonds into a layer structure.
