DFT calculations predict that M I Ag II F 3 perovskites undergo a series of pressure‐induced phase transitions towards post‐perovskite phases. These transitions are associated with changes of the first coordination sphere of Ag II and an increasing complexity of the [AgF 3 ] sublattice connectivity. Remarkably, the coordination number of the alkali metal ions decreases upon phase transitions. More information can be found in the Research Article by P. Kögerler, W. Grochala, and co‐workers (DOI: 10.1002/chem.202200712).
