Zeolites and layered silicates are useful compounds with many technical applications.
The localization of tetraalkylammonium cations and F-mineralisor for two different zeolites (ZSM-5 and ZSM-11) in their as synth. form was carried out using XR- diffraction analysis (Rietveld refinement) supported by SS-NMR and TG. The tetraalkylammonium
cations are situated at the channel intersections. The fluorine atoms are located in cages of the silicate framework.
Variants of the hydrous layer silicate Na-RUB-18 were synthesized and structurally investigated. The structure of Ca-exchanged form of RUB-18 was refined using neutron diffraction. Two intercalation products of Na-RUB-18 with organic molecules alanin and
acetone were determined with spectroscopic (NMR, IR) and powder neutron diffraction experiments. Hydrogen bonds between the intercalate and the silanol groups of silicate layer were observed. The alanine molecule is present in zwitterionic form and is
coordinated by water molecules.
