Structural and vibrational properties of agrellite.

ABSTRACT: Agrellite, NaCa₂Si₄O₁₀F, is a tubular silicate mineral which crystal structure is characterized by extended [Si₈O₂₀]^8- tubes and has a two-dimensional channel system. The mineral is a representative of a complex silicate family which contains some structural voids but cannot be considered as microporous because of small channel widths. However, the channel system of such minerals is able to host single guest atoms, molecules or radicals which can affect their physical properties. Presently, the exact mechanism of such hosting is undetermined. However, such information could be quite useful for materials' application as zeolites as well as for a better understanding of their formation mechanisms. In this work we couple X-ray
