摘要

Two atom-precise silver nanoclusters[Ag25Cl2(Tab)14(PhCOO)11(DMF)4](PF6)12 (Ag25,DMF=N,N-dimethylformamide) and[Ag26Cl2(Tab)14(PhCOO)13(DMAc)4](PF6)11 (Ag26,DMAc=N,N-dimethylacetamide) were synthesized based on the electrically neutral thiolate protective ligand,4-(trimethylammonio)benzenethiolate (Tab).The weak Ag-S interaction in Tab-protected silver nanoclusters allows to insert or leave a single silver atom in the Ag-S skeleton through solvent-trigger core fragmentation and re-arrangement,thereby realizing the reversible conversion of Ag25 and Ag26 for the first time.
