In the title compound, C(19)H(15)N(3)O(3), the anilino and benzamide rings make dihedral angles of 10.66 (16) and 50.39 (16)°, respectively, with the nitro-substituted benzene ring. The nitro group is slightly twisted by 11.49 (17)° with respect to the attached benzene ring. There is an intra-molecular N-H⋯O hydrogen bond forming an S(6) ring. In the crystal, weak inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a chain parallel to the b axis. Futhermore, weak slipped π-π inter-actions [centroid-centroid distance = 3.819 (2) Å, inter-planar distance = 3.567 Å and offset angle [how is the offset angle defined?] = 21°] between the anilino ring and its symmetry-related counterpart may help to stabilize the packing.
在标题化合物C₁₉H₁₅N₃O₃中，苯胺基环和苯甲酰胺环与硝基取代的苯环的二面角分别为10.66 (16)°和50.39 (16)°。硝基相对于相连的苯环轻微扭曲11.49 (17)°。存在一个分子内N-H⋯O氢键形成一个S(6)环。在晶体中，弱的分子间N-H⋯O和C-H⋯O氢键将分子连接成平行于b轴的链。此外，苯胺基环与其对称相关的对应环之间的弱滑移π-π相互作用[质心-质心距离 = 3.819 (2) Å，平面间距离 = 3.567 Å，偏移角[偏移角如何定义？]= 21°]可能有助于稳定堆积。
