The determination of active sites in metal nanoclusters is of great significance for the in-depth understanding of the structural evolution and the mechanism of physicochemical properties. In this work, the surface active Ag2(SR)3 units of the Ag48Cl14(S-Adm)30 nanocluster are determined, and the active-site tailoring of this nanocluster gives rise to two derivative nanoclusters, i.e., the structure-maintained Ag48Cl14(S-Adm)26(S-c-C6H11)4 and the structure-growth Ag50Cl16(S-Adm)28(DPPP)2. Both Ag48 and Ag50 nanoclusters exhibit almost the same cluster framework, but the Ag2(S-Adm)3 active units are regulated to Ag3(S-Adm)2(DPPP)1Cl1 with the transformation from Ag48 to Ag50. The surface active sites on Ag48 are rationalized by analyzing its crystal structure and the ligand-exchange-induced cluster transformation. This study provides some inspiration toward the active-site tailoring of nanocluster surface structures, which is significant for the preparation of new cluster-based nanomaterials with customized structures and enhanced performance.

Ag 48和Ag 50纳米团簇：致力于纳米团簇表面结构的主动站点定制
金属纳米簇中活性部位的确定对于深入理解结构演变和理化性质的机理具有重要意义。在这项工作中，确定了Ag 48 Cl 14（S-Adm）30纳米团簇的表面活性Ag 2（SR）3单元，并且对该纳米团簇进行活性位点修饰产生了两个衍生的纳米团簇，即结构保持的Ag 48 Cl 14（S-Adm）26（S- c -C 6 H 11）4和结构生长的Ag 50 Cl 16（S-Adm）28（DPPP）2。Ag 48和Ag 50纳米簇都显示出几乎相同的簇构架，但是随着从Ag 48向Ag的转化，Ag 2（S-Adm）3活性单元被调节为Ag 3（S-Adm）2（DPPP）1 Cl 1。银50。Ag 48上的表面活性部位通过分析其晶体结构和配体交换诱导的簇转变来合理化。这项研究为纳米簇表面结构的活性位点定制提供了一些启发，这对于制备具有定制结构和增强性能的新型团簇型纳米材料具有重要意义。
