In the title compound, [Cu(C12H11N2O4)(2)(C10H14N2O)(2)(H2O)(2)], the Cu-II atom lies on a center of inversion and is coordinated by carboxylate O atoms, pyridine N atoms and two water molecules in an elongated octahedral geometry. The pyridine ring is oriented at a dihedral angle of 74.83 (12)degrees with respect to the benzene ring. Intramolecular O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonding is observed. The water molecule is a hydrogen-bond donor to the carbonyl O atom of an adjacent carboxylate group, generating a chain running along the a axis. One of the ethyl groups is disordered over two sets of sites in a 0.787 (5):0.213 ratio.
