In the title compound, C20H16N2O4, the mol-ecule adopts an E conformation about the N=C bond. There is an intra-molecular O-H⋯N hydrogen bond forming an S(6) ring motif. The nitro-benzene and benz-yloxy rings are inclined to the central benzene ring by 4.34 (10) and 27.66 (11)°, respectively, and to one another by 31.40 (12)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming zigzag chains along [001]. Within the chains there are C-H⋯π inter-actions present. The chains are linked via π-π inter-actions [inter-centroid distance = 3.7048 (15) Å], forming slabs parallel to the bc plane.
在标题化合物C₂₀H₁₆N₂O₄中，分子围绕N=C键采取E构象。存在一个分子内O-H⋯N氢键，形成一个S(6)环模式。硝基苯环和苄氧基环分别相对于中心苯环倾斜4.34 (10)°和27.66 (11)°，且它们彼此之间倾斜31.40 (12)°。在晶体中，分子通过C-H⋯O氢键相连，沿[001]方向形成锯齿链。在这些链中存在C-H⋯π相互作用。这些链通过π-π相互作用相连[质心间距 = 3.7048 (15) Å]，形成平行于bc平面的层板。
