Trapping a [W O ] Decatungstate Anion in an Ag Nanowheel.

Compound [Ag (W O )(S Bu) (CF COO) ](CF COO)  ⋅ 6H O (1) was synthesized through a one-pot method. This is the first case of isolating a new silver thiolate cluster containing a [W O ] template which transforms from WO polyoxoanion through a self-assembly process. The anionic nature of the reduced [W O ] template and the effective silver-oxygen interaction contribute to the formation of the Ag nanowheel in 1. The luminescence, photocatalytic activity and electrochemistry properties of 1 were studied.
