Trapping a [W₁₀O₃₂]⁶⁻ Decatungstate Anion in an Ag₄₄ Nanowheel

Abstract

Compound[Ag 44 (W 10 O 32 )(S t Bu) 24 (CF 3 COO) 8 ](CF 3 COO) 6 • 6H 2 O (1) was synthesized through a one-pot method. This is the first case of isolating a new silver thiolate cluster containing a [W 10 O 32 ] 6À template which transforms from WO 4 2À polyoxoanion through a self-assembly process. The anionic nature of the reduced [W 10 O 32 ] 6À template and the effective silver-oxygen interaction contribute to the formation of the Ag 44 nanowheel in 1. The luminescence, photocatalytic activity and electrochemistry properties of 1 were studied.[a] J.

Solvent-Mediated Separation and Reversible Transformation of 1D Supramolecular Polymorphs Built from [W10O32]4– Templated 48-Nuclei Silver(I) Cluster

“…As shown in Figure 1 WO 4 2− precursor or directly originated from the raw material of ( n Bu 4 N) 4 W 10 O 32 (Supporting Information), is different from previously reported doubly reduced [W 10 O 32 ] 6− species in Zhou's work even though the configuration is the same. 57 In comparison with the [W 10 O 32 ] 6− template in Ag 44 , [W 10 O 32 ] 4− in Ag 48 here displayed less negative charge resulting in weaker electrostatic interaction with the surrounding Ag + . This can be confirmed by the Ag−O W bond length.…”

“…And the Ag···Ag interactions (2.900–3.274 Å) further consolidate the structure. Interestingly, the [W 10 O 32 ] 4– template with all W in +6 oxidization state, which is either generated in situ from the WO 4 2– precursor or directly originated from the raw material of ( n Bu 4 N) 4 W 10 O 32 (Supporting Information), is different from previously reported doubly reduced [W 10 O 32 ] 6– species in Zhou’s work even though the configuration is the same . In comparison with the [W 10 O 32 ] 6– template in Ag 44 , [W 10 O 32 ] 4– in Ag 48 here displayed less negative charge resulting in weaker electrostatic interaction with the surrounding Ag + .…”

Carboxylate Ligand‐supported Agn (n=21 and 24) Alkynyl Clusters Induced by Single/Double Carbonate Ions

“…The presence of compounds 1 and 2 can improve the photocatalytic decomposition rate of MB proved by a blank experiment. [88] Compounds 1 and 2 contain an energy band structure, and when the energy of the incident light is greater than the forbidden band width during xenon lamp irradiation, electrons are excited from the valence band to the conduction band to produce photogenerated electrons and holes in the valence band at the same time. Then these photogenerated electrons and holes react with O 2 , OH À , and H 2 O and produce •OH, •O 2 À , etc.…”

Synthesis and Proton Conductivity of Two Molybdate Polymers Based on [Mo8O26]4− Anions

“…[7] Recently, polyoxometalates (POMs) have attracted extensive attention in the fields of photochemistry, electronic devices, proton conductors, catalysis, and material science due to their excellent structural versatility. [8][9][10][11] POMs have abundant oxygen surface for charge transfer and have strong proton retention capability for PEMFCs. [12][13][14] In 2018, Khashab designed the Metal-Oxo Cluster within Cluster with [P 8 W 48 ] as the host and Al III ion as the guest.…”
