Bottom Line: Weak C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-centroid distance = 3.7269 (14) Å] help to establish the packing.Intra-molecular N-H⋯O hydrogen bonds are also observed.On one of the rings, the Br atom is disordered over two equivalent positions of the phenyl ring [occupancy ratio 0.8734 (10):0.1266 (10).

ABSTRACT
The title compound, C(14)H(11)BrN(4)O(4), contains 3-bromo-phenyl and 2,4-dinitro-phenyl groups on opposite sides of a hydrazone unit and crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the two ring systems in each mol-ecule are 2.0 (1) and 2.5 (4)°. Weak C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-centroid distance = 3.7269 (14) Å] help to establish the packing. Intra-molecular N-H⋯O hydrogen bonds are also observed. On one of the rings, the Br atom is disordered over two equivalent positions of the phenyl ring [occupancy ratio 0.8734 (10):0.1266 (10).
