Nested Keplerian architecture of [Cu₅₈H₂₀(SPr)₃₆(PPh₃)₈]²⁺ nanoclusters

This article explores the challenges in synthesizing highly symmetric Cu(I)–thiolate nanoclusters and reports a nested Keplerian architecture of [Cu₅₈H₂₀(SPr)₃₆(PPh₃)₈]²⁺ (Pr = CH₂CH₂CH₃). The structure is made up of five concentric polyhedra of Cu(I) atoms, which create enough space to accommodate five ligand shells all within a range of 2 nm. This fascinating structural architecture is also linked to the unique photoluminescence properties of the nanoclusters.
