摘要

基于{As4W40}的结构特点，采用简单材料水热法合成了冠状四核Ag-POM Na24[Ag3.4Na0.6(As4W40O140)]·82H2O(1)。化合物1的聚阴离子由嵌在环配体{As4W40}中的四核银簇和由Na+连接形成的三维框架组成。此外，化合物1具有优异的质子导电性，在90% RH， 358 K时，其最佳导电性为2.24 × 10−2 S cm−1。此外，它在加热-冷却循环中表现出出色的循环稳定性和超过68小时的耐久性。

Crown-type tetranuclear Ag-POM exhibits excellent proton conductivity performance†

A crown-type tetranuclear Ag-POM, Na₂₄[Ag_3.4Na_0.6(As₄W₄₀O₁₄₀)]·82H₂O (1), was synthesized based on the structural features of {As₄W₄₀} using simple materials through the hydrothermal method. The polyanion of compound 1 consists of a tetranuclear silver cluster embedded in the cyclic ligand {As₄W₄₀} and the polyanions linked by Na⁺ to form a 3D framework. Moreover, compound 1 exhibits excellent proton conductivity, with an optimal conductivity of 2.24 × 10⁻² S cm⁻¹ at 90% RH, 358 K. Furthermore, it demonstrates outstanding cycling stability during heating–cooling cycles and durability over 68 h.
