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) A for the C—C bonds close to the imino group are appreciably longer than the average distance of 1.377 (2) A for the rest of the C—C bonds in the ring. The overlapped arrangement and separation of 3.379 (8) A between parallel aromatic rings suggest the existence of a π–π-stacking interaction between neighboring molecules.
