چکیده
In the title compound, [Fe(C(5)H(5))(C(15)H(11)N(4)O(4))], the dinitro-phenyl and cyclo-penta-dienyl rings make dihedral angles of 53.61 (6) and 23.11 (9)°, respectively, with the pyrazole unit. The two cyclo-penta-dienyl rings are in an eclipsed conformation. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions, which link mol-ecules into chains parallel to the b axis.

The title structure, C(15)H(7)N(7)O(10)·C(3)H(6)O, was prepared by penta-nitration 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 mol-ecule, 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 int...
