Crystal structure of 4-formyl-2-nitrophenyl 4-chloro-2-nitrobenzoate

Abstract

In the title compound, C14H7ClN2O7, the central ester moiety is essentially planar, with an r.m.s. deviation of 0.0113 Å. The ester group is twisted away from the chloro- and formyl-substituted rings by 84.60 (9) and 88.55 (9)°, respectively. The crystal packing shows intermolecular C—H...O interactions. These interactions generate R22(20) and R44(22) edge-fused rings parallel to (20-2).
