In the title compound, [Fe(C5H5)(C16H14N3O3)], the pyrazoline ring and the substituted cyclopentadienyl ring are nearly coplanar, with a dihedral angle of 8.17 (2)degrees, while the nitro-substituted benzene ring is twisted out of the pyrazoline ring plane by 70.76 (1)degrees. The molecules in the crystal structure are held together by three intermolecular C-H center dot center dot center dot O hydrogen bonds. There is also an intramolecular C-H center dot center dot center dot N hydrogen bond. The H atoms of the methyl group are disordered equally over two positions.
