Crystals of the title compound, C16H14N4O4, were obtained from a condensation reaction of benzylideneacetone and 2,4-dinitrophenylhydrazine. The molecule has a nearly planar structure with a dihedral angle of 7.57 (4)° between the dinitrophenyl and benzylidene mean planes. Within the dinitrophenyl moiety, the distances of 1.420 (2) and 1.411 (3) Å for the C—C bonds near the imine group are longer than the average distance of 1.374 (3) Å for the other C—C bonds in the same benzene ring. The short N—C distance of 1.338 (2) Å indicates electron delocalization between the imine group and dinitrophenyl ring.
