A 1.87‐eV energy gap between the lowest energy excitation maximum and the emission maximum in solution was found for the novel hexanuclear gold( I ) sulfido complex 1 (Ar= p ‐CH 3 C 6 H 4 ), which has a heterocubane‐type structure. Besides this abnormally large Stokes shift of around 15 000 cm −1 , 1 exhibits intense orange luminescence in the solid state.
