4-Formyl-2-nitro­phenyl 3-nitro-2-methyl­benzoate

In the title formyl nitro aryl benzoate derivative, C₁₅H₁₀N₂O₇, the benzene rings form a dihedral angle of 4.96 (3)°. The mean plane of the central ester group, C—O—C–(=O)—C (r.m.s. deviation = 0.0484 Å), is twisted away from the formyl nitro aryl and benzoate rings by 46.61 (5) and 49.93 (5)°, respectively. In the crystal, the mol­ecules are packed forming C—H...O inter­actions in chains which propagate along [010]. Edge-fused R³₃(15) rings are generated along this direction.
