The title compound, [Fe(C44H8F20N4)]·2C6H6, contains a four-coordinated FeII atom, which lies on a center of symmetry. The porphyrin macrocycle is planar, and the Fe-N bond distances are in the range 1.9891 (13)-1.9982 (13) Å. The spin state of the FeII atom is intermediate (S = 1), as confirmed by NMR spectroscopy. The asymmetric unit contains two half benzene molecules, each lying about an independent inversion centre; one of the benzene rings is located just below (and by inversion symmetry, another is just above) the Fe atom, where it interacts weakly with the porphyrin ring.
