Main Group Chemistry:
Synthesis, structural, spectroscopic and bonding investigation of small
molecule compounds of boron, silicon, phosphorus and sulfur.
Isoelectronic relations. Exploitation of sulfur, phosphorus and arsenic
synthons in the construction of polymetallic compounds.
Metal-Metal Bonds and Clusters: New metal carbonyls. Synthesis and structural chemistry of heterometallic clusters. Cluster chirality. Metal exchange. Interconversions of organic substrates in the ligand sphere of di- and trinuclear complexes as models for catalytic processes.
Electron Transfer Systems: Synthesis and redox investigations of polynuclear complexes. Cyanide-linked arrays of ET-active metal centres. Electrochemistry, metal-metal charge transfer, structural and spectroscopic consequences of cyanide/isocyanide linkage isomerism and of electron transfer.Zinc Chemistry: Coordination chemistry of zinc related to its biological functions: synthesis, solid state and solution structures, thermodynamic data, reactivities, mechanistic and catalytic investigations. Models for zinc-containing proteases, phosphatases, lactamases, thiolate transferases, alcohol dehydrogenase, carbonic anhydrase and nucleic acid constituents.
