title: Crystal structure of 4-formyl-2-nitro-phenyl 4-chloro-2-nitro-benzoate.
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 inter-molecular C-H⋯O inter-actions. These inter-actions generate R 2 (2)(20) and R 4 (4)(22) edge-fused rings parallel to (20-2).
