Abstract: In the title compound, [Fe(C₅H₅)(C₁₅H₁₁N₄O₄)], the dinitrophenyl and cyclopentadienyl rings make dihedral angles of 53.61 (6) and 23.11 (9)°, respectively, with the pyrazole unit. The two cyclopentadienyl rings are in an eclipsed conformation. The crystal structure is stabilized by intermolecular C-HO interactions, which link molecules into chains parallel to the b axis.
