Site-specific substitution in atomically precise carboranethiol-protected nanoclusters and concomitant changes in electronic properties.

ABSTRACT: We report the synthesis of [Ag₁₇(o₁-CBT)₁₂]^3- abbreviated as Ag₁₇, a stable 8e⁻ anionic cluster with a unique Ag@Ag₁₂@Ag₄ core-shell structure, where o₁-CBT is ortho-carborane-1-thiol. By substituting Ag atoms with Au and/or Cu at specific sites we created isostructural clusters [AuAg₁₆(o₁-CBT)₁₂]^3- (AuAg₁₆), [Ag₁₃Cu₄(o₁-CBT)₁₂]^3- (Ag₁₃Cu₄) and [AuAg₁₂Cu₄(o₁-CBT)₁₂]^3- (AuAg₁₂Cu₄). These substitutions make systematic modulation of their structural and electronic properties. We show that Au preferent
