1-(Butan-2-ylidene)-2-(2-nitrophenyl)hydrazine
Abstract
Crystals of the title compound, C10H13N3O2, were obtained from a condensation reaction of butan-2-one and 1-(2-nitrophenyl)hydrazine. The molecule exhibits a nearly coplanar structure, except for the methyl and methylene H atoms, the largest deviations from the mean plane defined by all non-H atoms, except for the nitro group, being 0.120 (2) Å for one of the nitro O atoms. Intramolecular N—H...O hydrogen bonding helps to establish the molecular configuration.
