Isobutyraldehyde 2,4-dinitrophenylhydrazone

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

Abstract: Crystals of the title compound, C₁₀H₁₂N₄O₄, were obtained from a condensation reaction of isobutyraldehyde and 2,4-dinitrophenylhydrazine. The molecule exists in an E configuration. In the dinitrophenyl moiety, the average distance of 1.419  (3)  Å for the aromatic C-C bonds adjacent to the imino group is appreciably longer than the average distance of 1.375  (3)  Å for the other aromatic C-C bonds in the same ring. The overlapped arrangement and separations of 3.387  (15) and 3.369  (15)  Å between parallel rings suggest the existence of --stacking interactions between neighboring molecules.
