The central motivation of the present work is the development of a more detailed atomic-level picture of the local structure of these systems, as the insights obtainable with commonly used experimental methods are limited. While this is primarily of fundamental interest, the findings could eventually contribute to an improved understanding of the formation of zeolites and zeotypes during fluoride-mediated synthesis, which might aid the development of new or improved synthesis strategies. Furthermore, the presence of local distortions could also affect potential applications of these materials, especially those related to the dielectric properties.
