摘要：

X-Ray structure analysis reveals that in the crystalline silicate hydrates with the approximate chemical compositions [NPhMe(3)](6)[Si8O18(OH)(2)].38.7H(2)O and [NBnMe(3)](8)[Si8O20].53.6H(2)O (Bn = benzyl) cube-shaped octameric silicate anions and water molecules are linked via hydrogen bonds to form 3D mixed anionic host frameworks with channel systems; the interionic O...CH3(N) anion-cation interactions observed in the heteronetwork clathrates are of particular interest with regard to a very recently proposed mechanism for the formation of mesoporous silicate materials (M41S).
