The title compound, [Cu(C7H5O3)(2)(C6H6N2O)(2)(H2O)(2)], is a crystallographically centrosymmetric complex in which pyridine N and carboxylate and water O atoms form a tetragonally Jahn-Teller-distorted octahedron about the Cu-II ion with bond distances of 1.956 (2), 2.011 (2) and 2.575 (2) Angstrom. The noncoordinated carboxylate O atoms form hydrogen bonds with the amide N and water O atoms [O ... O 2.705 (4) and O ... N 2.888(3) Angstrom].
