En route from Metal Alkoxides to Metal Oxides: Metal Oxo/Alkoxo Clusters
by
Ulrich Schubert
Institute of Materials Chemistry, TU Wien Getreidemarkt 9, A-1060 Wien, Austria
Metal oxo/alkoxo clusters can be formed when metal alkoxides are slowly reacted with a limited amount of water (in a kind of “mini sol-gel process”), such as ambient humidity or – better controllable – generated by waterproducing organic reactions. Oxo clusters with stabilizing organic surface groups are not only interesting building blocks for materials syntheses (e.g., MOFs or hybrid polymers) and possibly intermediates in sol-gel processes, they are also molecular models for sol-gel processes and materials in general. A big advantage is that the clusters can be investigated by methods of molecular chemistry and crystallography, contrary to common sol-gel materials. The seminar will mainly focus on two issues: (i) phenomena related to the coordination chemistry of the organic ligands and (ii) the gradual evolution of cluster structures from small to big .
