N′-(4-Chlorobenzylidene)-2-hydroxybenzohydrazide

Abstract

The title molecule, C14H11ClN2O2, adopts a trans configuration with respect to the C=N double bond. An intramolecular N—H...O hydrogen bond contributes to molecular conformation and the two benzene rings form a dihedral angle of 17.9 (8)°. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecules into chains running along [10overline{1}].
