アブストラクト The structural and dynamical aspects of alkylammonium salts of a silicodecatungstate [(CH3)4N]4[ﾎｳ-SiW10O34(H2O)2], [(n-C3H7)4N]4[ﾎｳ-SiW10O34(H2O)2], [(n-C4H9)4N]4[ﾎｳ-SiW10O34(H2O)2], and [(n-C5H11)4N]4[ﾎｳ-SiW10O34(H2O)2] were investigated. The results of sorption isotherms, XRD analyses, and solid-state NMR spectroscopy show that facile sorption of solvent mols., flexibility of structures, and high mobility of alkylammonium cations are crucial to the uniform distribution of reactant and oxidant mols. throughout the bulk solid, which are related to the high catalytic activities for epoxidn. of alkenes.
