The asymetric unit of the title compound, [Fe(C5H5)(C17H13N2)], contains two independent molecules whose conformations differ, especially in the 4-{(pyridin-4-yl)methylidene]amino}phenyl unit where one is flipped by almost 180°. The cyclopentadienyl rings of the ferrocene unit also exhibit different staggered conformations: in one molecule the conformation is staggered by 9.43 (2)° and in the other by 24.46 (1)° from an ideal eclipsed geometry. The plane of the benzene ring is tilted away from the ferrocene group in both molecules, with dihedral angles of 6.97 (1) and 10.30 (2)°. The benzene ring is also slightly twisted from the plane of the pyridine ring, with dihedral angles of 5.98 (2) and 6.51 (2)° in the two molecules.
