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) A for the two C—C bonds adjacent to the imino group are appreciably longer than the average distance of 1.377 (2) A for the other aromatic C—C bonds in the same benzene ring. The crystal packing involves π–π stacking effects.
