Cyclohexanone 2,4-dinitrophenylhydrazone

S. Shan, D.-J. Xu and W.-X. Hu

Abstract: Crystals of the title compound, C₁₂H₁₄N₄O₄ were obtained by a condensation reaction between cyclohexanone and 2,4-dinitrophenylhydrazine. Within the dinitrophenyl group, the distances of 1.420 (2) and 1.422 (2) Å for the C-C bonds close to the imino group are appreciably longer than the average distance of 1.377 (2) Å for the rest of the C-C bonds in the ring. The overlapped arrangement and separation of 3.379 (8) Å between parallel aromatic rings suggest the existence of a --stacking interaction between neighboring molecules.
