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.
在非平面标题化合物C₁₆H₁₄N₂O₂中，苯环之间的二面角为16.67 (8)°。发现亚胺键[1.286 (2) Å]和乙烯键[1.335 (2) Å]均为E构型。酰胺O原子和H原子呈反式排列，并且注意到存在分子内羟基O—H⋯N氢键。晶体堆积中N—H⋯O(羟基)氢键的形成导致沿b轴形成螺旋链。由于这些链通过C—H⋯O相互作用相连，在ab平面上形成了超分子层。
