Abstract

We report a method for heavy doping of the Au₂₅(SR)₁₈ nanocluster (where R = C₆H₁₁) with silver through the Ag(I)–thiolate complex induced size/structure transformation of Au₂₃(SR)₁₆⁻ into Au_25–xAg_x(SR)₁₈⁻. X-ray crystallographic analysis revealed that Ag dopants are distributed not only in the icosahedral core but also in the surface staple motifs; the latter was not achieved in earlier studies of alloy Au_25–xAg_x nanoclusters.
