catena-Poly[[[(3,5-dimethyl-1H-pyrazole)copper(II)]-μ-{N-[1-(2-oxidophenyl)ethylidene]-l-valinato}] methanol monosolvate]

Abstract

The asymmetric unit of the title compound, {[Cu(C13H15NO3)(C5H8N2)]·CH3OH}n, contains two complex molecules and two solvent molecules. Each CuII ion is in a distorted square-pyramidal coordination with one N and two O atoms from the Schiff base ligand and one N atom from the heterocycle in the basal positions and one carboxylate O atom from a neighbouring ligand in the apical position. The apical Cu—O bonds are much longer than the basal Cu—O and Cu—N bonds. The carboxylate groups of the Schiff base ligands bridge the CuII ions, forming helical chains along [100]. The crystal packing is stabilized by intermolecular O—H...O and N—H...O hydrogen bonds.
