Abstract

Novel twinned-FCC clusters were designed via Au 13 core and fusion strategy. Au 182 / 188 exhibited metallicity, revealing reduced Au-atom threshold for metallicity in this configuration.

• A pair of diphosphine-protected gold nanoclusters differing by a single gold atom on the kernel surface
