Gold and sulfur assemble into small, stable anionic clusters that are either hollow or contain a single atom in the center, according to theoretical work published in ACS Nano that describes the structures and electronic properties of this class of clusters for the first time (DOI: 10.1021/nn103217z). The study, which focused on gold sulfide clusters containing up to 15 gold atoms, deepens understanding of the composition, stability, and other properties of metal-based clusters. . . .
