Advances in Structurally Characterized Lanthanide Alkoxide, Aryloxide, and Silyloxide Compounds

Synthesis and Characterization of New Pentacoordinate Iron‐Based Aryloxide Complexes

“…For several decades, intensive research in the chemistry of metal alkoxides or aryloxides [1][2][3][4][5][6][7][8] has developed, because of their interesting potential to serve many different applications for precursors of oxide materials such as LiCoO 2 , [7,9] as catalysts, [10][11][12][13] or as conducting materials. [9,14,15] Metal alkoxides have also been proposed as good precursors for ceramic materials based on high-purity metal oxides, because of their high solubility, low decomposition temperatures, [16] cross linking ability, and ease of modification.…”

“…[9,14,15] Metal alkoxides have also been proposed as good precursors for ceramic materials based on high-purity metal oxides, because of their high solubility, low decomposition temperatures, [16] cross linking ability, and ease of modification. [6,17] Several methods have been reported for the synthesis of metal alkoxides and aryloxides. [2][3][4]6] The synthetic method depends generally on the electronegativity of the metal concerned.…”

“…[6,17] Several methods have been reported for the synthesis of metal alkoxides and aryloxides. [2][3][4]6] The synthetic method depends generally on the electronegativity of the metal concerned. High electropositive metals, such as alkali, alkaline earth metals, and lanthanides, react directly with alcohols to liberate a hydrogen molecule and the corresponding metal alkoxide/aryloxide.…”

Structure of a hepta-nuclear termetallic oxo-alkoxide: Eu3K3TiO2(OBut)11(OMe/OH)(HOBut)

“…Metal alkoxides have attracted much interest of materials scientists owing to their versatility as precursors to advanced multi-component ceramic materials prepared via sol-gel processing or chemical vapour deposition [1][2][3][4][5][6]. In sol-gel processing, use of alkoxides often allows for facile complete hydrolysis of the alkoxo ligands to yield inorganic gels or nano-particles that can be converted to oxide thin films and nano-particles at low temperatures in a controlled manner.…”

“…Yet, although great advances have been made in alkoxide chemistry during recent years they still make up a class of compounds where much remains to explore to develop a level of understanding where molecular structures can be predicted [2][3][4][5][6]. Exploration of the various structures encountered among homoand heterometallic alkoxides and oxo-alkoxides can provide information about the structure-directing factors, and thus aid in the optimising of heterometallic ceramic precursors and selective catalysts.…”
