In the presence of different cations, reactions of [SbBr₆]³⁻ and I₂ result in a new family of diverse supramolecular 1D polyiodide‐bromoantimonate networks. The coordination number of Sb, as well as geometry of assembling {I_x}ⁿ⁻ polyhalide units, can vary, resulting in unprecedented structural types. The nature of I⋅⋅⋅Br interactions was studied by DFT calculations; estimated energy values are 1.6–6.9 kcal mol⁻¹. Some of the compounds showed strong photoconductivity in thin films, suggesting multiple feasible applications in optoelectronics and solar energy conversion.

新型的聚碘-溴锑酸（III）配合物家族：阳离子驱动的光导性金属-多卤化物骨架的自组装。

在存在不同的阳离子的情况下，[SbBr ₆ ] ³⁻和I _2的反应产生了一个新的家族，其中包括超分子一维多碘-溴锑酸网络。Sb的配位数，以及组装{I的几何_X } ^{ñ -}多卤化物单位，可以变化，从而导致了前所未有的结构类型。通过DFT计算研究了I⋅⋅⋅Br相互作用的性质。估计的能量值为1.6–6.9 kcal mol ^-1。一些化合物在薄膜中显示出很强的光电导性，表明在光电和太阳能转换中有多种可行的应用。
