Abstract(summary):

The asymmetric unit of the title compound, {[Cu(C(13)H(15)NO(3))(C(5)H(8)N(2))]center dot 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 center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds.
