Abstract

A new silver nanocluster, formulated as Ag₄₂(SBu^t)₂₄, was prepared by a NaSbF₆-mediated two-phase ligand exchange method. The total structure adopts a quasi-tetrahedral symmetry with a three-layered tetrahedral (T_d) Ag₁₀ kernel. Furthermore, with the ligand-etching method, Ag₄₂(SBu^t)₂₄ can be transformed into Ag₆₁(SC₆H₁₁)₄₀Cl, whose kernel structure corresponds to a face-fused bi-tetrahedral Ag₁₄.
