Abstract:
Herein, we report the synthesis and characterization of Fe3Co6S8L6 (L = Ph2PN(-)Tol), a sulfide analogue of the previously reported selenide cluster Fe3Co6Se8L6. Structural, spectroscopic, and electrochemical studies reveal that substitution of Se with S contracts the cluster core, increases the affinity for exogenous ligand binding at the Fe edge sites, and leads to a dramatic increase in the catalytic activity towards asymmetric carbodiimide formation from tosyl azide and tert-butyl isocyanide.

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.
