A second polymorph of aqua-{4-chloro-2-[(pyridin-2-ylmeth-yl)imino-meth-yl]-phenolato}copper(II) nitrate mono-hydrate.

ABSTRACT: The title complex, [Cu(C(13)H(10)ClN(2)O)(H(2)O)]NO(3)·H(2)O, was obtained by the reaction of 5-chloro-salicyl-aldehyde, 2-(amino-meth-yl)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 P2(1)/c. The Cu(II) 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, mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds to form chains along the a axis.
