Catena-Poly[[[(3,5-dimethyl-1H-pyrazole)-copper(II)]-?-{N-[1-(2-oxidophen-yl)ethyl-idene]-l-valinato}] methanol monosolvate].

ABSTRACT: 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 mol-ecules and two solvent mol-ecules. 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 carboxyl-ate 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 carboxyl-ate groups of the Schiff base ligands bridge the Cu(II) ions, forming helical chains along [100]. The crystal packing is stabilized by inter-molecular O-H?O and N-H?O hydrogen bonds.
