Abstract:
The title compound, [Fe(C(8)H(5))(C(22)H(16)P)(C(3)H(9)P)(3)], was synthesized by the addition of phenyl-ethine to a solution of the parent methyl iron complex Fe(CH(3)){P(C(6)H(5))(2)(C(10)H(6))}(PMe(3))(3) at 213 K, accompanied by evolution of methane. The coordination around the iron center can be described as slightly distorted octa-hedral [Fe-P 2.2485 (12)-2.2902 (12) Å; Fe-C 1.918 (5), 2.015 (4) Å], with a meridional arrangement of the trimethyl-phosphine ligands and the introduced terminal alkinyl-ligand trans to the P(Ph)(2)-anchoring group.

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.
Metal-Ligand Bonds
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...

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
