Following the initial analysis of the occurrence/absence of dynamic disorder and its dependence on temperature, it is insightful to take a closer look at the fluoride displacements associated with the individual dynamic events. To this end, both the average positions and the evolution of the atomic coordinates over time were analysed for those anions that undergo dynamic events. For the representative cases that are discussed in the following, a visualization of the fluoride trajectory plotted into the average structure of the surrounding cage is presented. Additionally, the fourth section of the Supporting Information contains plots of the time-averaged fluoride locations as well as the evolution of the relevant atomic coordinates. Since no dynamic events occur in NON, it does not feature in this analysis. However, representative individual trajectories obtained at the three temperatures considered are shown in Figure to exemplify the typical behavior of fluoride anions in this system. Although an increase in temperature leads to larger displacements from the equilibrium position (reflected by an increase in the RMSD from about 0.22 Å at 298 K to about 0.27 Å at 473 K), the equilibrium position remains essentially the same (reflected by a virtual constant F-Si bond length in the average structures).
