In the title compound, C(15)H(14)N(2)O(2), the 2,3-dimethyl-anilinic and benzaldehyde groups are planar, with r.m.s. deviations of 0.0101 and 0.0241 Å, respectively, and are oriented at a dihedral angle of 11.69 (3)°. The nitro group is inclined to the benzaldehyde group by 34.02 (9)°. The mol-ecule adopts an E configuration about the C=N bond. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, giving rise to the formation of zigzag polymeric chains extending along [010]. They are also linked by C-H⋯π, and π-π inter-actions [centroid-centroid distance of 3.7185 (11) Å] involving symmetry-related aniline and benzene rings. The H atoms of the ortho-methyl group are disordered over two sites with a refined occupancy ratio of 0.69 (2):0.31 (2).
在标题化合物C₁₅H₁₄N₂O₂中，2,3 - 二甲基苯胺基和苯甲醛基团是平面的，均方根偏差分别为0.0101和0.0241 Å，且二者呈11.69(3)°的二面角取向。硝基与苯甲醛基团呈34.02(9)°的倾斜角。分子围绕C=N键采取E构型。在晶体中，分子通过C—H⋯O相互作用连接，形成沿[010]方向延伸的锯齿状聚合物链。它们还通过C—H⋯π和π - π相互作用[质心 - 质心距离为3.7185(11) Å]相连，涉及对称相关的苯胺环和苯环。邻位甲基的H原子在两个位置上无序分布，精修占有率为0.69(2):0.31(2)。
