(2) The previous computational study dealt exclusively with models containing the highly symmetric tetramethylammonium (TMA) cation as OSDA. However, AST-type systems like octadecasil and AlPO4-16 can also be synthesised using the less symmetric quinuclidinium (QNU) cation. Given its very different molecular structure, notably the presence of a terminal -NH group, different framework-OSDA interactions can be anticipated, especially in terms of hydrogen bonding. To this end, TMA-and QNU-containing models are compared to investigate if and how the organic cation affects the equilibrium position and dynamics of the fluoride anions.
