3,5-Bis(2,4-dinitrophenyl)-4-nitro-1H-pyrazole acetone monosolvate

Abstract

The title structure, C15H7N7O10·C3H6O, was prepared by pentanitration of 3,5-diphenyl-1H-pyrazole. The proton attached to a pyrazole N atom forms a hydrogen bond with the O atom of the acetone solvent molecule, owing to the NO2 enhanced acidity of the proton. The NO2 group on the phenyl C atom is twisted by 33.9 (2)° from coplanarity with the ring in order to avoid a short intramolecular O...O contact with an O atom of an adjacent pyrazole-bonded NO2 group.
