Cl原子可以作为金属纳米团簇的最内层核心、外围配体或抗衡离子。本文报道了富Cl的[Ag_（52）（SAdm）_（31）Cl_（13）]~（2+）的结构测定。Cl与AdmSH的比率与其它纳米团簇的比率相比是相当高的。在结构上，9个氯原子，存在于内核和表面基序的中间层，作为桥接配体，以维持整个结构的鲁棒性。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配体在金属纳米团簇结构构建中的调控作用。
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.
