We report the decomposition of the PtAg(SPhCl) nanocluster into a crown-like PtAg(SR) (SR = 2,4-SPhCl and 4-SPhBr) complex. UV-vis spectra and single crystal X-ray diffraction were used to track the structure-conversion process. Based on the total structure, the differences in ligand exchange rates at different sites and the effects on the stability were mapped out. This work can not only help us understand the ligand exchange behavior of the clusters, but also provide experimental support for the design of stable metal clusters.
我们报道了PtAg(SPhCl)纳米团簇分解为冠状PtAg(SR)（SR = 2,4 - SPhCl和4 - SPhBr）配合物的过程。利用紫外可见光谱和单晶X射线衍射来追踪结构转变过程。基于整体结构，绘制出不同位点配体交换速率的差异及其对稳定性的影响。这项工作不仅有助于我们理解团簇的配体交换行为，还为稳定金属团簇的设计提供了实验支持。
