Coinage clusters with octanuclear {Au I 2 Ag I Cu I }2 rings were synthesized with a flexible tetraphosphine ligand, via a dinuclear Au I intermediate. Through a stepwise construction, the Ag I ions in the ring are replaced by Cu I and Au I ions to afford a series of {Au I 2 M I Cu I }2 rings (M=Au I , Ag I , Cu I ), in which the ring shape and size as well as luminous properties are finely modulated by the M element.
