[2-Hydroxy-N′-(4-oxo-4-phenylbutan-2-ylidene)benzohydrazidato(2−)]pyridinecopper(II)

Abstract

The mononuclear title complex, [Cu(C17H14N2O3)(C5H5N)], was synthesized by the reaction of CuCl2·2H2O with N-(4-oxo-4-phenylbutan-2-ylidene)benzohydrazide (H2L). The central CuII atom exhibits a distorted square-planar coordination geometry, defined by two O atoms, one N atom from the ligand and one pyridine N atom with Cu—N distances of 1.874 (4) and 1.963 (4) Å, while the Cu—O distances are 1.857 (3) and 1.890 (3) Å. An intramolecular O—H...N interaction occurs.
