Abstract:
Metal sulfur bonds are largely found in metalloenzymes, and lead to
specific spectroscopic properties and original reactivity in comparison with complexes containing only N-or/and O-based ligands. On the other hand, synthetic complexes with metal-thiolate bonds have revealed some interesting properties that could be involved in biological processes. However, to rationalize the reactivity of such
systems, a deep investigation of their electronic properties is required. In this context, we have synthesized and characterized series of aliphatic thiolate complexes with various transition metal
ions (Ni, Co, Zn, Cu, Mn, V) [1–3]. Their electronic properties have
been explored via different spectroscopic techniques combined with
quantum chemistry. More recently, we went a step further by looking at their reactivity, especially their ability to activate small
molecules, or to form disulfide bridges and how this process can be
controlled.
