3-Bromo-N′-(2-hydroxybenzylidene)benzohydrazide

The title molecule, C14H11BrN2O2, displays a trans configuration about the C=N and C—N bonds. The dihedral angle between the two benzene rings is 18.5 (3)°. An intramolecular O—H...N hydrogen bond is observed. In the crystal structure, the molecules are linked into a chain along the c axis by N—H...O and C—H...O hydrogen bonds.
