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

In the title formyl nitro aryl benzoate derivative, CH NO, 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 = 0.0484Å), 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 R 3(15) rings are generated along this direction
