Rh₁₉^-: A high-spin super-octahedron cluster.

ABSTRACT: Probing atomic clusters with magic numbers is of supreme importance but challenging in cluster science. Pronounced stability of a metal cluster often arises from coincident geometric and electronic shell closures. However, transition metal clusters do not simply abide by this constraint. Here, we report the finding of a magic-number cluster Rh₁₉^- with prominent inertness in the sufficient gas-collision reactions. Photoelectron spectroscopy experiments and global-minimum structure search have determined the geometry of Rh₁₉^- to be a regular O_h‑[Rh@Rh₁₂@Rh₆]^- with unusual high-spin electronic configuration. The distinct stability of such a strongly magnetic cluster Rh₁₉^- consi
