N′-(2-Chlorobenzylidene)-4-hydroxybenzohydrazide

In the molecule of the title compound, C14H11ClN2O2, the dihedral angle between the benzene rings is 30.53 (4)°. In the crystal structure, intermolecular O—H...O and N—H...O hydrogen bonds link the molecules into a two-dimensional network. π–π contacts between benzene rings [centroid–centroid distance = 3.619 (1) Å] may further stabilize the structure. The crystal studied was found to be an inversion twin.
