Fully Cationized Gold Clusters: Synthesis of Au₂₅(SR⁺)₁₈

Abstract

Although many thiolate-protected Au clusters with different numbers of Au atoms and a variety of thiolate ligands have been synthesized, to date there has been no report of a fully cationized Au cluster protected with cationic thiolates. Herein, we report the synthesis of the first member of a new series of thiolate-protected Au cluster molecules: a fully cationized Au₂₅(SR⁺)₁₈ cluster.
