Cover Feature: High‐Pressure and High‐Temperature Dion–Jacobson Layered Perovskite Polymorphs of KWO3F (Chem. Eur. J. 43/2023)

Abstract

The syntheses and crystal structures of the three polymorphs of KWO3F are shown. The layered perovskite structures are depicted as cubes stacked in different manners, with the colors of the cube faces indicating the anion site occupation (red for oxygen and green for fluorine). The background refers to the synthesis conditions for each of the three polymorphs (left: solvothermal synthesis, middle: high-temperature synthesis, right: high-pressure/high-temperature synthesis). More information can be found in the Research Article by H. Huppertz and co-workers (DOI: 10.1002/chem.202301098).
