Alkoxides: As a Single Source Precursors

For the last two decades, there has been a growing interest in the development of the chemistry of mixed-metal bi- and polynuclear alkoxo and alkoxo-organometallic complexes. Such interest derives from their fascinating structural chemistry, interesting catalytic properties, and high potential for industrial applications. The fact that most of the heterometallic alkoxo species can generate bimetallic or multimetallic oxides has resulted in high research activity in the field. The most attractive applicable routes for preparation of oxide materials are those involving alkoxides and their derivatives. First of all, their attractiveness lies in the fact that they are easily accessible and consist inexpensive compounds. Furthermore, alkoxide ligands are easily removable via thermal treatments. Finally, these compounds already have metal-oxygen bonds established. Molecular precursors derive from alkoxide complexes can generate ceramic materials in a single step (so-called single-source precursors – SSPs). In the case of bi- or polyoxides, such materials deliver appropriate metal elements of a final product eliminating the need to match the reaction rates required from a multicomponent precursor mixture.
