摘　　要：Two atom-precise silver nanoclusters[Ag_(25)Cl_2(Tab)_(14)(Ph COO)_(11)(DMF)_4](PF_6)_(12)(Ag_(25),DMF=N,N-dimethylformamide)and[Ag_(26)Cl_2(Tab)_(14)(Ph COO)_(13)(DMAc)_4](PF_6)_(11)(Ag_(26),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 Ag_(25)and Ag_(26)for the first time.
