Cagelike sil-[1] and germsesquioxanes [2] are in the research focus of many scientific teams worldwide. Diverse forms of sesquioxane (REO1.5, E = Si or Ge) ligands – from monomeric to polycyclic – provide numerous types of metallacomplexes. Particularly efficient synthetic approach implies use of different auxiliary organic (N,N-, P,P-, N,O-, O,O-) ligands [3]. Plenty of structural forms endows metallasesquioxanes with practically important properties, e.g. catalytic [4], magnetic [5], photophysical [6] ones. Lecture will discuss main results of our group in synthesis of cagelike metallasesquioxanes as well as features of their catalytic activity, magnetic effects and luminescent behavior.
