Structural links between zeolite-type and clathrate hydrate-type materials

Abstract

A reconsideration of crystallographic data from the literature reveals that some crystalline alkylammonium(alumino)silicate hydrates are host—guest compounds, which provides a structural link between zeolite-type and clathrate hydrate-type materials; such compounds may be of significant interest as crystalline model compounds in studies on amorphous silica hydrogels and on the atomic scale mechanisms of zeolite crystallization (e.g. the template effect).
