3-Chloro-N′-(4-hy­droxy­benzyl­idene)benzohydrazide

The title compound, C14H11ClN2O2, was prepared by the reaction of 4-hy­droxy­benzaldehyde with 3-chloro­benzo­hydrazide in methanol. The dihedral angle between the two benzene rings is 38.2 (2)°. In the crystal, mol­ecules are linked through inter­molecular N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds, forming layers lying parallel to the bc plane
