Lone-Pair-Induced Structural Ordering in the Mixed-Valent 0D Metal-Halides Rb₂₃Bi^III _x Sb^III _7-x Sb^V ₂Cl₅₄ (0 ≤ x ≤ 7).

ABSTRACT: Mixed-valent metal-halides containing ns² lone pairs may exhibit intense visible absorption, while zero-dimensional (0D) ns²-based metal-chlorides are generally colorless but have demonstrated promising optoelectronic properties suitable for thermometry and radiation detection. Here, we report solvothermally synthesized mixed-valent 0D metal-halides Rb₂₃Bi^III _x Sb^III _7-x Sb^V ₂Cl₅₄ (0 ≤ x ≤ 7). Rb₂₃Sb^III ₇Sb^V ₂Cl₅₄ crystallizes in an orthorhombic space group (Cmcm) with a unique, layered 0D structure driven by the arrangement of the 5s² lone pairs of the Sb^III<
