We care for fundamental studies of structure-property relationships of coordination compounds:
We aim at making use of the intriguing electronic and chemical properties of M-S bonds which include:
- Covalent M-S bonding: e--transfer along M-S units
- Bronsted-basicity of M-S: H+-transfer between sulphur and metal
- Redox-activity of M-S structure: formation of mixed-valent radical-ligand structures
[thiolate-M(n+)-thiyl]+ vs [thiolate-M(n+1)+-thiolate]+
To what effect?
- M-S structures are functional units that enable rapid electron transfer in Nature, e.g. 2Fe-ferredoxins or CuA-site
- Proton transfer between sulphur and the metal provides an efficient mechanism for
the formation of highly reactive metal-hydride that is the key reactive component in the
evolution and oxidation of H2 such as in natural [NiFe]-hydrogenase.
- Radical-ligand complexes feature intriguing electronic structures and optical properties
and have a widespread spectrum of applications such as in catalysis or as electrochromic
