Robust Enantiomeric Two-Dimensional Assembly of Atomically Precise Silver Clusters.

The facile syntheses of enantiomeric atomically precise silver clusters starting from achiral ligands remain a substantial challenge to explore. In this work, a pair of atomically precise enantiomers of /-[AgCl(PrS)S(CHCOO)HO] (, PrS = isopropanethiolate) clusters have been synthesized using a viable solvothermal approach. The chirality of the resulting enantiomeric clusters is attributed to the asymmetric arrangement of surface achiral ligands. Both enantiomers could form the two-dimensional (2D) assemblies via intercluster interactions of basic building blocks containing AgS moieties, PrS-Ag motifs, and S linkers. Such a small ligand-induced 2D assembly greatly contributes to the enhancement of thermal stability and photocatalytic activity of clusters, providing possibilities for exploring robust coinage cluster-based assembly with attractive catalytic properties.
