Trapping a [W₁₀ O₃₂ ]^6- Decatungstate Anion in an Ag₄₄ Nanowheel

Compound [Ag₄₄ (W₁₀ O₃₂ )(S^t Bu)₂₄ (CF₃ COO)₈ ](CF₃ COO)₆  ⋅ 6H₂ O (1) was synthesized through a one-pot method. This is the first case of isolating a new silver thiolate cluster containing a [W₁₀ O₃₂ ]^6- template which transforms from WO₄ ^2- polyoxoanion through a self-assembly process. The anionic nature of the reduced [W₁₀ O₃₂ ]^6- template and the effective silver-oxygen interaction contribute to the formation of the Ag₄₄ nanowheel in 1. The luminescence, photocatalytic activity and electrochemistry properties of 1 were studied.
