This lecture will present some actual aspects of cage-like metallasilsesquioxanes, namely unusual compounds with simultaneous manifestation of metal cluster and organosilicon compound properties. The unique ability of Cu(II)-, Mn(II)-, Co(II)-, Ni(II)-, Fe(III)-containing silsesquioxanes to form extraordinary polyhedral compounds and coordination polymers will be demonstrated. Viewing of different synthetical approaches to cage metallasilsesquioxanes of different shape, nuclearity and composition will be given. Several examples of cage’ complexation with various N- and P-containing ligands will be shown. Application of Cu(II)-containing cages in catalysis of amide formation and hydrocarbons oxidation will be discussed. Dependency of cage’ magnetic properties from composition, geometry and ligand surrounding will be presented as well.
