Dynamic structural engineering of ferrocene-functionalized Ag₂₀ nanoclusters for enhanced CO₂ electroreduction performance.

ABSTRACT: The integration of organometallic motifs with metal nanoclusters offers a powerful strategy for constructing hybrid catalysts with precisely tunable active sites. Here, we report the synthesis of a 20-silver nanocluster, Ag₂₀-Fc, via cooperative coordination between thiacalix[4]arene (TC4A) and ferrocenylacetylene ligands. The cluster adopts a distinctive sandwich-like architecture, featuring two Ag₅@TC4A units flanking a ferrocenyl-stabilized Ag₁₀ core, and exhibits excellent structural tunability. Ligand engineering allows replacement of the ferrocenylacetylene units with methoxyphenylacetylene (Ag₂₀-OPh) or phenylacetylene (Ag₂₀-Ph), while preserving the core framework. Electrospray ionization mass spectrometry reveals dynami
