With no dynamic events at RT and 2/4 events at 373/473 K, the results for CHA are most similar to those of STF, indicating that the observed disorder of fluoride anions over 12 positions in the d6r cage is of a static nature at room temperature. This agrees with the absence of any broad signal in the range of δiso = -115 to -150 ppm in the Si NMR spectrum. Given the prominent disorder in the crystal structure, with many fluoride sites in relatively close proximity, the lack of evidence for dynamic disorder appears somewhat surprising. However, these observations highlight that the time-averaged crystal structure alone allows for no reliable conclusions regarding the dynamic behavior. This is especially true for sites with low occupancy, where the atomic displacement parameters refined from XRD data must be regarded with caution.
