3-Chloro-N′-[(2-hydroxynaphthalen-1-yl)methylidene]benzohydrazide

Abstract

The title compound, C18H13ClN2O2, was prepared by the reaction of 2-hydroxy-1-naphthaldehyde with 3-chlorobenzohydrazide in methanol. An intramolecular O—H...N hydrogen bond influences the molecular conformation; the benzene ring and naphthyl ring system form a dihedral angle of 17.1 (3)°. In the crystal, intermolecular N—H...O hydrogen bonds link the molecules into chains propagated in [101].
