Abstract: Crystals of the title compound, C₁₅H₁₃ClN₄O₆, were obtained from a condensation reaction of 2-chloro-3,4-dimethoxybenzaldehyde and 2,4-dinitrophenylhydrazine. Within the dinitrophenyl group, the distances of 1.413  (3) and 1.405  (3)  Å for the C-C bonds close to the imino group are appreciably longer than the average distance of 1.372  (4)  Å for other aromatic C-C bonds in the same benzene ring. The benzene rings in the molecule are nearly coplanar, and the overlapped arrangement of benzene rings of neighboring molecules shows the existence of a - stacking interaction.
