The title structure, C 15 H 7 N 7 O 10 ·C 3 H 6 O, was prepared by penta­nitration of 3,5-diphenyl-1 H -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.
