N2 - Aluminophosphonates and phosphates possess two and threedimensional structures related to zeolitic materials. New synthetic methods for their preparation are currently intensively studied with the aim of extending the number of structural types and chemical compositions. The majority of the procedures is based on aqueous chemistry. The aim of our studies is to synthesize aluminophosphonates and phosphates by several different nonhydrolytic routes. In one approach we prepared molecular building blocks, such as 4R and D4R, from metal alkyls, alkoxides, halides and amides, and phosphoric, phosphonic and phosphinic acids and their esters. Several new derivatives were characterized by spectroscopic and structural methods and we studied their chemical reactivity in substitution reactions at the vertices of these polygonal and polyhedral molecules. The other emphasis of our work is on finding suitable solution or thermal methods to convert these molecular precursors to solid materials. In this direction, nonhydrolytic reactions of the 4R derivatives with Lewis acids and bases were studied to obtain aluminophosphate materials with extended frameworks. Sonochemically activated reactions of aluminum precursors, such as triisopropoxide and tris(acetylacetonate), in inert (tetraglyme) and reactive (tributyl phosphate) solvents were found to provide oxidic and phosphate materials, respectively.
