Synthesis, Structures, Bonding, and Reactions of Imido-Selenium and -Tellurium Compounds,The focus is on providing an understanding of the unusual features of the structures, bonding and reactivities of these labile chalcogen-nitrogen compounds. Trends in properties within the chalcogen group are made by including comparisons with analogous sulfur-nitrogen compounds, where appropriate.

A New Class of Paramagnetics: 1,2,5-Chalcogenadiazolidyl Salts as Potential Building Blocks for Mol, with special emphasis on their design, synthesis, and characterization using X-ray diffraction, EPR spectroscopy and magnetometry in combination with DFT and post-HF calculations. Prospects of the salts as building blocks for molecular magnets and conductors are discussed.

Particular emphasis is laid on the relevance of selenium transport to tissue specific functions, unexpected roles of seemingly well understood selenoproteins, and potential roles of less characterized ones.

Redox and Related Coordination Chemistry of PNP- and PCP-Bridged Selenium and Tellurium-Centred Ligtion complexes of these multi-chalcogen-centred ligands with coinage metals are discussed. DFT calculations provide insights into the different behaviour of the N- and C-bridged anions upon oxidation, as well as an understanding of the nature of the elongated chalcogen-chalcogen bonds that are a common feature for both systems.

Employing these .-halides can eliminate pathways for side reaction, and are easily displaced allowing for the isolation of a variety of highly charged homoleptic coordination complexes.
