This oxide is stabilized by cation vacancies leading to a La1+x/3K1−xMnWO6 stoichiometry. Compositional modulation on both the K and La layers are revealed in the high-angle annular dark-field STEM (HAADF-STEM) images. The compositional modulation within the La layer is coupled with the modulation of the octahedral tilting, which is exposed by imaging of the anion sublattice in annular bright-field STEM (ABFSTEM) images. These complex modulations are accommodated in a 5√2ap × 5√2ap × 2ap perovskite-type structureengjournal articlehttps://doi.org/10.1021/jacs.1c07426restricted access546Lanthanum compoundsCiencias23 Química
