Single-Atom Control of Aromaticity and Excited-State Dynamics in Endohedral Zirconium-Antimony Zintl Clusters.
Three-dimensional (3D) aromaticity provides a powerful framework for understanding the stability and electronic structures of superatomic clusters, yet how such aromaticity evolves during atom-by-atom structural growth remains poorly understood. Herein, we report two endohedral zirconium-antimony Zintl clusters, [Zr@Sb...
