Abstract: One naphthalene-1,4-dicarboxylate dianion in the title compound, [Cu₂(C₁₂H₆O₄)₂(C₁₄H₈N₄)₂]·4H₂O, bridges two N-heterocycle-chelated Cu atoms whereas the other one bridges four N-heterocycle-chelated Cu atoms, linking them into a flat carboxylate-bridged layer. The two independent Cu atoms show square-pyramidal coordination. Water molecules occupy the space between adjacent layers; they are possibly disordered, and their H atoms were not located.
