coordination compounds - Opis:
- Completely condensed POSS compounds have a cage structure built of Si-O bonds, which makes their electronic properties similar to those of silica and silicates. Moreover, due to their relatively inelastic structure, they impose a coordination geometry on the metal atom, imitating the geometry imposed by silica. Due to the above-mentioned properties, homogeneous models based on silsesquioxanes may not only allow for a better understanding of the nature of heterogeneous catalysts at the molecular level, but also may act as valuable catalysts themselves. Many coordination compounds of main group metals, transition metals and lanthanides have already been obtained. From among the group 13 metals of which this work is concerned, coordination entities of boron, aluminum, gallium, thallium, and indium have been prepared and analyzed so far. They turned out to be suitable models for heterogeneous catalysts, in some cases showing catalytic properties themselves.
