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

The title structure, C(15)H(7)N(7)O(10)·C(3)H(6)O, 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 NO(2) enhanced acidity of the proton. The NO(2) group on the p...

Sumario:The title structure, C(15)H(7)N(7)O(10)·C(3)H(6)O, 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 NO(2) enhanced acidity of the proton. The NO(2) 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 NO(2) group.
