Anion Distribution, Structural Distortion, and Symmetry-Driven Optical Band Gap Bowing in Mixed Halide Cs(2)SnX(6) Vacancy Ordered Double Perovskites

[Image: see text] Mixed anion compounds in the Fm3̅m vacancy ordered perovskite structure were synthesized and characterized experimentally and computationally with a focus on compounds where A = Cs(+). Pure anion Cs(2)SnX(6) compounds were formed with X = Cl, Br, and I using a room temperature solu...
