On the structure and reactivity of large complexes of metals and metalloids. A quantum chemical study

In this thesis four challenging problems concerning metal- or metalloid-containing systems were studied in order to explain their properties, reactivities and selectivities. Presented applications include the analysis of the reaction paths of the dialkyl zinc additions to unsaturated aldehydes, the characterisation of unusual bonding patterns in metalloid clusters, calculations of the electronic structure of small nickel clusters as well as studies of oxygen activation by a cobalt complex.
