N-(4-Bromo-2-nitro­phenyl)-N-methyl-N'-(quinolin-4-yl­methyl­ene)­hydrazine

The title compound, C₁₇H₁₃BrN₄O₂, is non-planar, with a dihedral angle between the quinoline and substituted phenyl rings of 20.8 (1)°. The N—N bond distance [1.359 (3) Å] is close to the value of 1.350 (10) Å quoted for the N—N bond in pyridazinium [Allen et al. (1987). J. Chem. Soc. Perkin Trans. 2, pp. S1–19].
