In the title compound, C(14)H(12)N(4)O(5), an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. The dihedral angle between the two benzene rings is 3.91 (3)°, which shows the mol-ecule is almost planar. The para-nitro group is twisted from the benzene ring to which it is attached, making a dihedral angle of 8.50 (9)°. In the crystal structure, mol-ecules are linked together by inter-molecular C-H⋯O and inter-molecular three-centred O⋯O [2.8646 (12)-2.9213 (11) Å] and O⋯N [3.0518 (11) Å] inter-actions. The crystal structure is further stabilized by inter-molecular π-π inter-actions [centroid-to-centroid distances 3.5708 (6)-3.9728 (12) Å].
在标题化合物C₁₄H₁₂N₄O₅中，分子内的N-H⋯O氢键形成了一个S(6)环 motif。两个苯环之间的二面角为3.91 (3)°，这表明分子几乎是平面的。对硝基相对于其所连接的苯环发生扭曲，二面角为8.50 (9)°。在晶体结构中，分子通过分子间的C-H⋯O以及分子间的三中心O⋯O [2.8646 (12)-2.9213 (11) Å] 和O⋯N [3.0518 (11) Å] 相互作用连接在一起。晶体结构通过分子间的π-π相互作用 [质心到质心距离3.5708 (6)-3.9728 (12) Å] 进一步稳定。
