The principal molecule of the title molecule, C 12 H 8 -ClN 3 O 3 ÁC 3 H 7 NO, is essentially planar. The two benzene rings make a dihedral angle of only 6.9 (1) . The nitro group is slightly twisted with respect to the benzene ring to which it is attached [3.7 ( 1) ]. The dimethylformamide solvent

In the title compound, C~16~H~15~BrN~4~O~6~·C~3~H~7~NO, the substituted vanillin group makes a dihedral angle of 7.58 (10)° with the nitrophenylhydrazine mean plane. A bifurcated intra/intermolecular N—H...(O,O) hydrogen bond and two C—H...O interactions help to establish the molecular conformation
