چکیده
In the title compound, {[Cu(C(11)H(5)NO(4))(H(2)O)(2)]·H(2)O}(n), the Cu(II) ion is five-coordinated by two O atoms and one N atom of two symmetry-related quinoline-2,3-dicarboxyl-ate ligands, and two water mol-ecules. The water mol-ecules occupy basal and apical positions of the square-pyramidal coordination polyhedron. Each quinoline-2,3-dicarboxyl-ate dianion bridges two adjacent Cu(II) ions, forming a polymeric chain along [010]. The chains are further connected via O-H⋯O hydrogen-bonding inter-actions and quinoline ring π-π inter-actions [centroid-centroid distance = 3.725 (4) Å], generating a three-dimensional structure. Lattice water mol-ecules participate in the crystal structure via O-H⋯O hydrogen bonds.

In the title compound, {[Cu(C(7)H(3)NO(4))(H(2)O)(3)]·H(2)O}(n), the Cu(II) ion is bonded to three water mol-ecules, one N,O-bidentate pyridine-2,3-dicarboxyl-ate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO(5) octa-hedral geometry. The bridging ligand results in an infinite chain. A network of O-H⋯O hydrogen bonds helps to establish the crystal structure.
