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

The asymmetric unit of the title compound, {[Cu(C(13)H(15)NO(3))(C(5)H(8)N(2))]·CH(3)OH}(n), contains two complex mol­ecules and two solvent mol­ecules. Each Cu(II) 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 Cu(II) ions, forming helical chains along [100]. The crystal packing is stabilized by inter­molecular O—H⋯O and N—H⋯O hydrogen bonds.
