3-Chloro-N'-(4-hy-droxy-benzyl-idene)benzohydrazide.

The title compound, C(14)H(11)ClN(2)O(2), was prepared by the reaction of 4-hy-droxy-benzaldehyde with 3-chloro-benzo-hydrazide in methanol. The dihedral angle between the two benzene rings is 38.2†(2)°. In the crystal, mol-ecules are linked through inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, forming layers lying parallel to the bc plane.
