title: 4-Formyl-2-nitro-phenyl 4-bromo-benzoate.
abstract: In the title compound, C14H8BrNO5, the benzene rings form a dihedral angle of 62.90 (7)°. The central ester group is twisted away from the nitro-substituted and bromo-substituted rings by 71.67 (7) and 8.78 (15)°, respectively. The nitro group forms a dihedral angle of 7.77 (16)° with the benzene ring to which it is attached. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, forming C(12) chains which run along [001]. Halogen-halogen inter-actions [Br⋯Br = 3.523 (3) Å] within the chains stabilized by C-H⋯O inter-actions are observed.
