چکیده
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 hydrogen bonds form inversion dimers. In addition, π-π stacking inter-actions between the bromo- and dinitro-substituted rings [centroid-centroid separation = 3.768 (2) Å] are observed.

The title compound, C(15)H(10)BrFO, is isostructural with (2E)-1-(4-chloro-phen-yl)-3-(4-fluoro-phen-yl)prop-2-en-1-one [Qiu et al. (2006 ▶). Acta Cryst. E62, o3525-o3526], but the structures of other dihalogen analogues, without fluorine, are different, although they are also isostructural within the series. The mol-ecule is approximately flat, the dihedral angle between the ring planes being ...
