Given the multitude of factors at play, and the difficulties in establishing generalizable relationships, it appears that no universal crystal-chemical rules could be devised that would allow for an a priori prediction of the most probable fluoride position in a given all-silica zeolite without further input from experiments and/or DFT calculations. Additionally, the analysis of the AIMD results has shown that the inclusion of thermal motion will tend to reduce the energy differences between different sites, in some cases (IFR, CHA) leading to dynamic disorder of fluoride anions over positions having large energy differences ΔErel according to the static calculations. This aspect should be kept in mind when evaluating the energetic ordering of different fluoride locations.
