Propiophenone 2,4-dinitrophenylhydrazone

S. Shan, D.-J. Xu, J.-Y. Wu and M. Y. Chiang

Abstract: Crystals of the title compound, C₁₅H₁₄N₄O₄, were obtained from a condensation reaction between 2,4-dinitrophenylhydrazine and propiophenone. The compound crystallizes in an E configuration. Within the dinitrophenyl ring the distances [average 1.417  (4)  Å] of C-C bonds ipso to the amino group are significantly longer than the average distance of 1.375  (4)  Å for the other C-C bonds in the same phenyl ring. The van der Waals contact between the methyl and nitro groups from neighboring molecules results in the deviation of the ethyl group from the phenyl plane of the propiophenone group.
