Abstract:
The title compound, [Fe(C(44)H(8)F(20)N(4))].2C(6)H(6), contains a four-coordinated Fe(II) 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) A. The spin state of the Fe(II) 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.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
