Synthesis, characterization and crystal structure of the water-soluble, all-inorganic composition, A,beta-Keggin triniobium(V)-substituted polyoxotungstate
Triniobium(V) -substituted beta -Keggin polyoxotungstate, K-7[A,beta -SiW9Nb3O40](.)6H(2)O, as a soluble metal-oxide analogue and a metal-oxide support of the polyoxoanion-supported organometallic complexes, was synthesized, and the crystal and molecular structures of this polyoxoanion containing the Keggin A,beta -SiW9 unit were successfully determined for the first time.
