Most of the differences in the dynamic behavior of fluoride anions among the zeolites studied can be explained by differences in the local environment: Where relatively short contacts to nextnearest neighboring Si atoms are present, attractive interactions with these atoms facilitate the occurrence of dynamic events, whereas systems in which all F•••Si distances are relatively long (> 2.8 Å) do not exhibit RT dynamic disorder. Cooperative effects, i.e., interactions with several of the surrounding Si atoms, appear to play a decisive role in enhancing the probability of dynamic events, as illustrated for STT. Although the possible occurrence of dynamic disorder depends primarily on the geometry of the cages in which the fluoride anions reside, attractive interactions with the OSDA can suppress the dynamic motion in systems where the local environment as such would favor dynamic jumps between Si sites, as observed for CHA and (in previous work) for MFI_(MTBA,F). Due to the much larger freedom of motion of the OSDA cations in comparison to framework atoms, the importance of this effect can be expected to decrease with temperature.
