抄録
This Account will focus on some recent aspects of the research performed in the author’s laboratory. Selected examples of complexes in which the ligands play an essential role in determining the molecular properties will be examined. Concerning the applications of these complexes, we will limit ourselves to some aspects related to the catalytic oligomerization of ethylene. In the search for such catalysts, we found that deprotonation of N,OH ligands chelated to Ni(II) with NaH can give rise to a range of heterometallic Na-Ni polynuclear complexes. In addition to their catalytic relevance, their magnetic properties were also investigated and have revealed in some cases Single Molecule Magnet behaviour. The diverse functions that co-catalysts may exert will be illustrated by the characterization of Cr(III) complexes obtained by reaction of fac-[Cr(NpyPNpy)Cl3] with typical co-catalysts such as MAO, EtAlCl2, AlMe3 and AlEt3. We will also discuss some polynuclear and cluster chemistry where a prediction of the nuclearity and composition of the metal cores remains difficult or impossible. This emphasizes the importance of basic research and the need to recognize the contribution of serendipity. The relevance of cluster chemistry to various fields of molecular synthesis and activation, catalysis and nanosciences, will also be mentioned.
