Symmetric Growth of Dual-Packed Kernel: Exploration of the Evolution of Au₄₀(SR)₂₄ to Au₄₉(SR)₂₇ and Au₅₈(SR)₃₀ Clusters via the 2e ^--Reduction Cluster Growth Mechanism.

ABSTRACT: The symmetric and periodic growth of metal core and ligand shell has been found in a number of ligand-protected metal clusters. So far, the principle of symmetric growth has been widely used to understand and predict the cluster structure evolution. In this work, based on the experimentally resolved crystal structure of Au₄₀(o-MBT)₂₄ and Au₄₉(2,4-DMBT)₂₇ clusters and a newly proposed two-electron (2e ^-) reduction cluster growth mechanism, the evolution pathway from the quasi-face-centered-cubic (fcc)-structured Au₄₀(SR)₂₄ cluster to the dual fcc- and nonfcc-packed Au₄₉(SR)₂₇ and Au₅₈(SR)₃₀ clusters was studied. The current research has clarified two importa
