The F-Ga RDFs obtained for GaPO4-AST show two maxima, indicating an off-centre displacement of the fluoride anions that is comparable to that observed in AlPO4-AST (Figure ). However, the maxima are less well separated, and significant g(r) values are observed between them even at 150 K, especially for GaPO4-AST_TMA. A visualisation of the average structures (Figures and) shows that d4r cages in which fluoride is bonded to a single Ga atom are more typical in GaPO4-AST_QNU, whereas configurations where fluoride is displaced towards one face with similar distances to two Ga atoms occur more frequently in GaPO4-AST_TMA. This distinct difference, which is qualitatively visible in the visualisation of individual fluoride trajectories (lower part of zeotypes also show a pyritohedron-like distortion, as observed above for GeO2-AST (bottom part of Figure ). In the TMA-containing system, neither fluoride displacements nor the distortions of the d4r cages are ordered in any way (Figure ). In GaPO4-AST_QNU, the same displacement pattern of the fluoride anions as in the corresponding AlPO4-AST system is observed, which, while being most pronounced at 150 K, persists up to 573 K (Figure ). In contrast, the distortions of the d4r cages have a random orientation, at variance with the findings for GeO2-AST_QNU. Apparently, framework-OSDA interactions have a larger influence on the preferential formation of Ga-F bonds than on the deformation of the d4r units in GaPO4-AST, and the two phenomena are not strictly coupled to each other.
