N'-(5-Chloro-2-hydroxybenzylidene)-4-methoxybenzohydrazide

Abstract: The asymmetric unit of the title compound, C15H13ClN2O3, contains two independent hydrazone molecules. Each molecule adopts an E configuration with respect to the methylidene unit and forms an intramolecular O-H...N hydrogen bond. The principal difference between the two unique molecules is the relative orientation of the two benzene rings, the dihedral angles between them being 4.0 (3) and 65.9 (3)°, respectively. In the crystal, molecules are linked through N-H...O hydrogen bonds, forming chains running along the c axis.
