Research on nanocluster transformation has generally focused on stable nanoclusters, while analysis of the structural evolutions of metastable nanoclusters just began to receive attention recently. Herein, we report the structural determination of a metastable Ag₂₇H₁₁(SPhMe₂)₁₂(DPPM)₆ nanocluster and its spontaneous transformation into a size-reduction Ag₈(SPhMe₂)₈(DPPM)₁ nanocluster as well as ligand-exchange-triggered transformation into a size-growth Ag₂₉(SSR)₁₂(DPPM)₄ nanocluster. The new structure of Ag₂₇ and its structural transformations hopefully provide some implication to the in-depth understanding of metastable nanoclusters.

亚稳态 Ag27 纳米团簇的结构测定及其向 Ag8 和 Ag29 纳米团簇的转化

纳米团簇转变的研究一般集中在稳定的纳米团簇上，而亚稳态纳米团簇的结构演化分析最近才开始受到关注。在此，我们报告了亚稳态 Ag ₂₇ H ₁₁ (SPhMe ₂ ) ₁₂ (DPPM) ₆纳米团簇的结构测定及其自发转变为尺寸减小的 Ag ₈ (SPhMe ₂ ) ₈ (DPPM) ₁纳米团簇以及配体-交换触发转变为尺寸增长的 Ag ₂₉ (SSR) ₁₂ (DPPM) ₄纳米团簇。Ag ₂₇的新结构及其结构转变有望为深入了解亚稳态纳米团簇提供一些启示。
