Abstract: In the title compound, {[Cu(C11H5NO4)(H2O)2]·H2O}n, the CuII ion is five-coordinated by two O atoms and one N atom of two symmetry-related quinoline-2,3-dicarboxylate ligands, and two water molecules. The water molecules occupy basal and apical positions of the square-pyramidal coordination polyhedron. Each quinoline-2,3-dicarboxylate dianion bridges two adjacent CuII ions, forming a polymeric chain along [010]. The chains are further connected via O-H...O hydrogen-bonding interactions and quinoline ring [pi]-[pi] interactions [centroid-centroid distance = 3.725 (4) Å], generating a three-dimensional structure. Lattice water molecules participate in the crystal structure via O-H...O hydrogen bonds.
