1-[(Bromo­meth­yl)(phen­yl)meth­ylene]-2-(2,4-dinitro­phen­yl)hydrazine

The title compound, C(14)H(11)BrN(4)O(4), comprises two crystallographically independent mol­ecules (A and B) in the asymmetric unit. In mol­ecule B, intra­molecular bifurcated N—H⋯O and N—H⋯Br hydrogen bonds and in mol­ecule A, an intra­molecular N—H⋯O hydrogen bond generate S(6) ring motifs. The dihedral angle between the phenyl and benzene rings is 5.44 (6) in mol­ecule A and 7.63 (6)° in mol­ecule B. The ortho- and meta-nitro substituents make dihedral angles of 6.67 (15) and 2.26 (15)° to the attached benzene ring in mol­ecule A and 6.37 (17) and 5.81 (16)° in mol­ecule B. The Br atom in mol­ecule B is disordered over two positions with a refined site-occupancy ratio of 0.61 (3):0.39 (3). Inter­esting features of the crystal structure are the short Br⋯N [3.257 (3)–3.294 (4) Å], Br⋯O [3.279 (3)–3.307 (4) Å] and O⋯O [2.9319 (16)–2.9995 (16) Å] contacts, which are shorter than the sum of the van der Waals radii of these atoms. The crystal structure is further stabilized by inter­molecular C—H⋯O and π–π inter­actions [centroid–centroid distances = 3.6643 (8)–3.8514 (8) Å].
