In the title mol-ecule, C(21)H(14)BrFN(4)O(4), the mean planes of the two nitro groups form dihedral angles of 3.1 (2) and 7.1 (5)° with the benzene ring to which they are attached. The dinitro-substituted ring forms dihedral angles of 8.6 (2) and 71.9 (2)° with the bromo- and fluoro-substituted benzene rings, respectively. The dihedral angle between the bromo- and fluoro-substituted benzene rings is 80.6 (2)°. There is an intra-molecular N-H⋯O hydrogen bond. In the crystal, pairs of weak C-H⋯O ...[more]
