Abstract: The title compound, [Fe₂(C₅H₅)₂(C₂₂H₂₀N₄O₂)], has been synthesized by the reaction of ferrocenoylacetone and butanedioic acid dihydrazide in ethanol. The dihedral angles between one pyrazole ring and the attached cyclopentadienyl ring and carbonyl plane are 33.5 (4) and 4.4 (8)°, respectively; for the other pyrazole ring, the corresponding angles are 29.5 (4) and 11.2 (8)°, respecively.
