(E)-4-Bromo-N'-(2-hydroxy-1-naphthylmethylene)benzohydrazide

Y.-P. Diao, Q.-H. Zhang, D.-C. Wang and X.-M. Deng

Abstract: The title compound, C₁₈H₁₃BrN₂O₂, was synthesized by the reaction of 2-hydroxy-1-naphthaldehyde with 4-bromobenzohydrazide. This Schiff base molecule has an E configuration about the C=N bond and is almost planar, the dihedral angle between the mean planes through the substituted benzene ring and the naphthyl system being 6.6 (2)°. There is an intramolecular O-HN hydrogen bond involving the naphthyl hydroxy substituent and the N' atom of the hydrazide group. In the crystal structure, molecules are linked through intermolecular N--HO hydrogen bonds to form chains extending along the b direction.
