Abstract An unusual metal-organic framework, {H[Ag(I)L][Mo(VI)4O13]}n (1) (L=(4-((1H-1,2,4-triazol-1-yl)methyl)phenyl)methanol)), has been obtained under ionothermal conditions. According to the single-crystal X-ray diffraction analysis, 1 is a new 3-D framework based on β-[Mo8O26]4− type polymolybdate anions with two kinds of channels (A and B) along the b-axes and c-axes in the framework. The neighboring inorganic Mo8-Ag chains are linked by the organic ligands through the Ag centers resulting in 2-D layers. These adjacent 2-D layers extend into a 3-D framework through Ag1 nodes and β-[Mo8O26]4− anions, respectively, resulting in a topological symbol (64 · 82)2(64 · 82). In addition, the gas adsorption, proton conduction and luminescent properties of 1 are also discussed in detail. Moreover, the electrochemical impedance spectroscopy (EIS) measurements show a conductivity (1.9 × 10−4 S cm−1 at 65 °C and 95% relative humidity (RH)), with an activation energy of 0.41 eV for 1. The mechanism of proton conduction for 1 is proved to be the vehicular mechanism. Graphical Abstract

基于经典 β-[Mo8O26]4− 阴离子的新型 3-D 骨架的电离热合成

摘要 一种不寻常的金属有机骨架，{H[Ag(I)L][Mo(VI)4O13]}n (1) (L=(4-((1H-1,2,4-triazol-1-yl )甲基)苯基)甲醇))，已在离子热条件下获得。根据单晶 X 射线衍射分析，1 是一种基于 β-[Mo8O26]4- 型多钼酸阴离子的新型 3-D 骨架，沿 b 轴和 c-具有两种通道（A 和 B）框架中的轴。相邻的无机 Mo8-Ag 链由有机配体通过 Ag 中心连接，形成二维层。这些相邻的 2-D 层分别通过 Ag1 节点和 β-[Mo8O26]4- 阴离子延伸到 3-D 框架中，从而产生拓扑符号 (64 · 82)2(64 · 82)。此外，还详细讨论了1的气体吸附、质子传导和发光特性。而且，电化学阻抗谱 (EIS) 测量显示电导率（在 65 °C 和 95% 相对湿度 (RH) 下为 1.9 × 10−4 S cm−1），1 的活化能为 0.41 eV。 质子传导的机制因为 1 被证明是车辆机制。图形概要
