3-Bromo-N′-(3,5-dichloro-2-hydroxybenzylidene)benzohydrazide

Abstract

The title compound, C14H9BrCl2N2O2, was prepared by the reaction of 3,5-dichloro-2-hydroxybenzaldehyde and 3-bromobenzohydrazide in methanol. The dihedral angle between the two benzene rings is 13.0 (2)°. An intramolecular O—H...N hydrogen bond is observed. The molecules are linked into chains along the c axis by intermolecular N—H...O hydrogen bonds.
