Abstract
In the structue of the title compound, C18H13ClN2O2, a new Schiff base, the dihedral angle between the benzene and naphthyl ring system mean planes is 22.5 (2)°. The molecule has an E configuration about the C=N bond, and an intramolecular hydrogen bond involving the hydoxyl substituent on the naphthyl ring and the N′ atom of the hydrazide. The crystal structure is stabilized by intermolecular N—H⋯O hydrogen bonds, forming one-dimensional chains running parallel to the a axis.

Summary
Key indicators: single-crystal X-ray study; T = 298 K; mean (C–C) = 0.003 A; R factor = 0.044; wR factor = 0.105; data-to-parameter ratio = 15.3. In the structue of the title compound, C18H13ClN2O2, a new Schiff base, the dihedral angle between the benzene and naphthyl ring system mean planes is 22.5 (2). The molecule has an E configuration about the C N bond, and an intramolecular hydrogen bond involving the hydoxyl substituent on the naphthyl ring and the N0 atom of the hydrazide. The crystal structure is stabilized by intermolecular N—HÁ Á ÁO hydrogen bonds, forming one-dimensional chains running parallel to the a axis.
