Nested Keplerian architecture of [Cu 58 H 20 (SPr) 36 (PPh 3 ) 8 ] 2+ nanoclusters.

This article explores the challenges in synthesizing highly symmetric Cu(I)-thiolate nanoclusters and reports a nested Keplerian architecture of [Cu 58 H 20 (SPr) 36 (PPh 3 ) 8 ] 2+ (Pr = CH 2 CH 2 CH 3 ). 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.
