[(E)-N'-(5-Chloro-2-oxidobenzyl-idene-κO)-3,4,5-trimeth-oxy-benzohydrazidato-κN',O](pyridine-κN)copper(II).

In the title compound, [Cu(C(17)H(15)ClN(2)O(5))(C(5)H(5)N)], the Cu(II) atom is coordinated by one N atom and two O atoms from an anionic salicyl-aldehyde benzoyl-hydrazone ligand and one pyridine N atom in a distorted square-planar geometry. The bonds displays the usual elongation with mean Cu-O and Cu-N bond lengths of 1.926 and 1.976 Å, respectively. The pyridine ring makes dihedral angles of 26.12 (13) and 11.08 (12)°, respectively, with the trimeth-oxy-phenyl and phenolate rings, which make a dihedral angle of 16.05 (12)° with one another.
