Abstract
X-Ray structure analysis reveals that in the crystalline silicate hydrates with the approximate chemical compositions [NPhMe3]6[Si8O18(OH)2]·38.7H2O and [NBnMe3]8[Si8O20]·53.6H2O (Bn = benzyl) cube-shaped octameric silicate anions and water molecules are linked via hydrogen bonds to form 3D mixed anionic host framework 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).Keywords
