The single‐crystal structure of [Au 9 (PPh 3 ) 8 ](NO 3 ) 3 was resolved for the first time with atomic resolution. The cluster has crystallographic D 2 and approximate molecular D 2 h skeletal symmetry derived from an icosahedron. Voltammetry of the Au 9 clusters in CH 2 Cl 2 reveals a 1.78‐eV energy gap between the first one‐electron oxidation peak and the first reduction peak. The UV/Vis and luminescence properties of Au 9 clusters were also investigated. The cluster solid shows two broad emission peaks at 579 nm and 853 nm, respectively, at room temperature.
