In the title CuII complex, [Cu(C7H3NO4)(C6H5NO2)(H2O)]·H2O, the environment of the Cu2+ ion is a distorted square pyramid with the axial site occupied by the O atom from the coordinated water molecule and the square base formed by two O and two N atoms from the tridentate anion and the neutral monodentate pyridine-3-carboxylic acid ligand. O—H⋯O hydrogen bonds, as well as π–π interactions [centroid–centroid distance = 3.945 (3) Å] contribute to the stabilization of this structure.
