(2E)-N'-[(E)-2-Hy-droxy-benzyl-idene]-3-phenyl-prop-2-enohydrazide.
In the non-planar title compound, C(16)H(14)N(2)O(2), 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 ethyl-ene [1.335 (2) Å] bonds. The amide O and H atoms are anti, and an intra-molecular hy-droxy O-H⋯N hydrogen bond is noted. The formation of N-H⋯O(hy-droxy) hydrogen bonds in the crystal packing leads to helical chains along the b axis. Supra-molecular layers in the ab plane are formed as the chains are linked by C-H⋯O inter-actions.
