Abstract:
At 296 (2) K, both complexed rings in the iron(II) complex cation of the title salt, [Fe(C(5)H(5))(C(16)H(10)O(2))]PF(6), are almost parallel [dihedral angle between planes = 2.4 (3)°]. The quaternary C atoms of the complexed arene ring are located at the longest distance from the Fe atom, with Fe-C distances of 2.112 (4) and 2.105 (3) Å, which are slightly longer than the average Fe-C distance for this ring (2.083 Å). The Fe ion is located 1.660 (1) and 1.543 (1) Å, respectively, from the cyclo-penta-dienyl and the complexed arene 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.
