Multinary Halogenido Bismuthates beyond the Double Perovskite Motif.

Both lead halide perovskites and bismuth-based double perovskites have generated intense research interest in the past few years. There is, however, a broader class of bismuthates that transcends the double perovskite motif. These multinary halogenido bismuthates remain severely underexplored and offer rich research opportunities with regard to new structure motifs and material properties.
