Abstract:
A coordination gadolinium(III) mononuclear complex involving the new redox-active tetrathiafulvaleneamido-2-pyrimidine-1-oxide is synthesized. The X-ray structure of the 1:3 gadolinium complex [Gd(hfac)(3)(TTF-CONH-2-Pym-1-oxide)(3)](CH(2)Cl(2)).0.5C(6)H(14) reveals that the coordination polyhedron of the paramagnetic 4f (S = (7)/(2)) Gd(III) ion can be described as a 4,4,4-tricapped trigonal prism. The three-coordinated TTF derivatives adopt a fac conformation with a pseudohelicoidal arrangement. A radical-cation salt of this new ligand is reported. Such a coordination complex is an innovative building block for the pi-f system and the introduction of new physical properties.

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.

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...
