Abstract
The title compound, C14H11BrN4O4, contains 3-bromophenyl and 2,4-dinitrophenyl groups on opposite sides of a hydrazone unit and crystallizes with two molecules in the asymmetric unit. The dihedral angles between the two ring systems in each molecule are 2.0 (1) and 2.5 (4)°. Weak C—H⋯O hydrogen bonds and weak π–π stacking interactions [centroid–centroid distance = 3.7269 (14) Å] help to establish the packing. Intramolecular 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).
