Abstract:
The title compound, [Fe(C(2)H(5)O)(C(36)H(44)N(4))], contains a five-coordinate iron-porphyrin complex with an axial eth-oxy ligand. The iron(III) atom is displaced by 0.504 (2) Å towards the eth-oxy ligand from the 24-atom mean plane of the porphyrin. The average Fe-N(p) distance is 2.078 (2) Å and the Fe-O distance is 1.8232 (18) Å. The eth-oxy C atoms are disordered in a 0.581 (12):0.419 (12) ratio. The bond angles of the Fe-O-C linkage are 128.6 (3) and 130.4 (3)°, respectively, for the major and minor occupancy C atoms.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
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.
