In the non-planar title compound, C16H14N2O2, the dihedral angle between the phenyl rings is 16.67 (8)°. An E conformation is found for each of the imine [1.286 (2) Å] and ethylene [1.335 (2) Å] bonds. The amide O and H atoms are anti, and an intramolecular hydroxy O—HN hydrogen bond is noted. The formation of N—HO(hydroxy) hydrogen bonds in the crystal packing leads to helical chains along the b axis. Supramolecular layers in the ab plane are formed as the chains are linked by C—HO interactions.

In the title compound, C16H14N2O, the dihedral angle between the phenyl rings is 25.48 (12)°. An E conformation is found for each of the imine [1.269 (3) Å] and ethylene [1.313 (3) Å] bonds. In the crystal, molecules are linked by N—HO hydrogen bonds, leading to zigzag chains along [010]. Supramolecular layers in the ab plane are formed, whereby the chains are linked by C—HN and C—Hπ interactions.
