Atomically Precise Enantiopure Bimetallic Janus Clusters.

ABSTRACT: Asymmetric bimetallic Janus nanocrystals with a side-by-side interface have unique properties and important applications. However, understanding their fundamental issues, including their formation mechanism, interfacial linkage, and related properties, remains challenging, as does the preparation of enantiopure samples. Atomically precise Janus bimetal nanoclusters would unequivocally resolve these issues, yet they have not been realized. Here, based on Au and transition metals (Cu/Cd), and employing an S/P biligand strategy, we prepare and structurally resolve four Janus nanoclusters, including racemate 6e Au ₈ /Cu ₄ , 6e R -/ S-Au ₈ /Cu ₄ enantiomers, and 2e racemat
