Abstract: Crystals of the title compound, C₁₄H₁₁ClN₄O₄, were obtained from a condensation reaction of m-chloroacetophenone and 2,4-dinitrophenylhydrazine. The two benzene rings of the title molecule have a dihedral angle of 16.17 (6)°. Within the dinitrophenyl moiety, the distances of 1.422 (3) and 1.415 (3) Å for the C-C bonds close to the imine group are appreciably longer than the average distance of 1.376 (3) Å for other aromatic C-C bonds in the same benzene ring. The overlapped arrangement of chlorophenyl rings of neighbouring molecules shows the existence of a - stacking interaction.
