(1-Ferrocenyl-4,4,4-trifluoro-butane-1,3-dionato-κO,O)bis-(triphenyl-phosphane)copper(I)
Abstract:
In the title mononuclear coordination complex, [CuFe(C(5)H(5))(C(9)H(5)F(3)O(2))(C(18)H(15)P)(2)], the Cu(I) ion is coordinated by the chelating β-diketonate 1-ferrocenyl-4,4,4-trifluoro-butane-1,3-dione ligand through two O atoms and the two datively bonded triphenyl-phosphane ligands resulting in a distorted tetra-hedral coordination sphere. The Cu(I) ion, together with its chelating butane-1,3-dione group, is mutually coplanar [greatest displacement of an atom from this plane = 0.037 (1) Å], and the Cu(I) ion lies slightly above [0.013 (1) Å] the plane. The overall geometry, including the bond distances and angles within the complex, corresponds to those of other reported copper(I) β-diketon-ates featuring organic groups at the β-diketonate ligand.

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.

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...
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.
