Abstract: In the title compound, {[Cu(C₁₂H₁₀O₈)(C₁₂H₈N₂)]·H₂O}_n, the Cu^II ion is five-coordinated by two N atoms from one phenanthroline ligand and three O atoms from three different H₂L^2- anions (H₄L is bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxylic acid) in a distorted square-pyramidal geometry. Each H₂L^2- ion bridges three Cu^II atoms to form a zigzag sheet parallel to the ab plane. The crystal structure is consolidated by O-HO hydrogen bonds.
