In the title nitroaryl benzoate derivative, C14H9NO5, the aromatic rings form a dihedral angle of 46.37 (8)°. The central ester moiety, -C-(C=O)-O-, is essentially planar (r.m.s. deviation for all non-H atoms = 0.0283 Å) and forms a dihedral angle of 54.06 (9)° with the 4-formyl-2-nitro-phenyl ring and 7.99 (19)° with the benzoate ring. In the crystal, mol-ecules are inter-twined by weak C-H⋯O inter-actions, forming helical chains along [100].
在标题化合物硝基芳基苯甲酸酯衍生物C₁₄H₉NO₅中，芳环形成的二面角为46.37 (8)°。中心酯部分-C-(C=O)-O-基本呈平面状（所有非H原子的均方根偏差 = 0.0283 Å），与4-甲酰基-2-硝基苯环形成的二面角为54.06 (9)°，与苯甲酸酯环形成的二面角为7.99 (19)°。在晶体中，分子通过弱C-H⋯O相互作用缠绕在一起，沿[100]形成螺旋链。
