Abstract: Crystals of the title compound, C₁₅H₁₄ClN₃O₄, were obtained from a condensation reaction of 2-chloro-3,4-dimethoxybenzaldehyde and 4-dinitrophenylhydrazine. Within the nitrophenyl moiety, the distances of 1.401  (2) and 1.399  (2)  Å for the two C-C bonds adjacent to the imino group are appreciably longer than the average distance of 1.377  (2)  Å for the other aromatic C-C bonds in the same benzene ring. The crystal packing involves - stacking effects.
