Cl atoms can serve as the innermost core, the peripheral ligand, or the counterions of metal nanoclusters. Herein, we report the structural determination a Cl-enriched [Ag₅₂(SAdm)₃₁Cl₁₃]²⁺. The ratio of Cl to AdmSH is quite high compared to those of other nanoclusters. Structurally, nine Cl atoms, existing at the interlayer of the inner kernel and the surface motif, serve as the bridging ligands to sustain the robustness of the whole structure. Interestingly, four Cl atoms on the motif structure can be substituted by Br. This work allows us to clear the regulation of Cl ligands in the structural construction of metal nanoclusters.

富氯 [Ag52(SAdm)31Cl13]2+ 纳米团簇的结构测定

Cl 原子可作为金属纳米团簇的最内核、外围配体或反离子。在此，我们报告了富氯 [Ag ₅₂ (SAdm) ₃₁ Cl ₁₃ ] ²⁺的结构测定。与其他纳米团簇相比，Cl 与 AdmSH 的比率相当高。在结构上，存在于内核和表面基序的夹层的九个 Cl 原子作为桥接配体以维持整个结构的稳健性。有趣的是，基序结构上的四个 Cl 原子可以被 Br 取代。这项工作使我们能够明确 Cl 配体在金属纳米簇结构构建中的调控。
