Core in cage : By using a DFT‐based basin‐hopping method, we found putative global minima for three gold sulfide nanoclusters, observed in mass spectrometry, that all show a symmetric core‐in‐cage structure: a metallic Au core inside a cage with S as vertices and Au at the edges (see figure). This core‐in‐cage structure is distinct from bulk gold sulfide. This work fills the knowledge gap regarding the structure of gold sulfide nanoclusters of ≈1 nm.
