Abstract: The title complex, [Cu(C13H10ClN2O)(H2O)]NO3·H2O, was obtained by the reaction of 5-chlorosalicylaldehyde, 2-(aminomethyl)pyridine and copper nitrate in methanol. The first reported polymorph of this complex was triclinic [Liang et al. (2010). Acta Cryst. E66, m40]. The present polymorph crystallized in the monoclinic space group P21/c. The CuII ion is in a square planar environment and is coordinated by one phenolate O, one imine N and one pyridine N atom of the tridentate Schiff base ligand and by one water O atom. In the crystal, molecules are linked through intermolecular O-HO hydrogen bonds to form chains along the a axis.
