摘要

我们通过一锅反应制备了一种非典型的含{Ru(C6H6)}的异多钼酸盐 Cs8K2Na2H4{[(C6H6)Ru]6Mo24O86}-35H2O (1)。化合物 1 的晶体学表征显示，它含有一个不同寻常的{Mo24O86}簇和六个{Ru(C6H6)}基团，是含{Ru(C6H6)}多氧金属盐领域中{Ru(C6H6)}基团数量最多的化合物。结果表明，化合物 1 在 90 °C 和 95% 相对湿度条件下显示出优异的质子传导性（9.8 × 10-3 S cm-1）。根据活化能大于 0.4 eV（1.47 eV）的计算结果，可以确定化合物 1 的质子传导过程符合 Vehicle 机理。更有趣的是，化合物 1 被用作催化剂实现了胺的异相氧化偶联，并在常温、可见光照射（400 nm）和氧气环境下实现了对 N-亚苄基苄胺的高产率（98.9%）。

A {Ru(C6H6)}-Containing Isopolymolybdate with Good Photocatalytic Activity for Oxidative Coupling of Amines, and Proton Conduction Properties

We present a nonclassical {Ru(C₆H₆)}-containing isopolymolybdate Cs₈K₂Na₂H₄{[(C₆H₆)Ru]₆Mo₂₄O₈₆}·35H₂O (1) via one-pot reaction. The crystallographic characterization of compound 1 revealed that it contains an unusual {Mo₂₄O₈₆} cluster together with six {Ru(C₆H₆)} groups, having the largest number of {Ru(C₆H₆)} groups within the field of {Ru(C₆H₆)}-containing polyoxometalates. Results showed that compound 1 displayed excellent proton conductivity (9.8 × 10^–3 S cm^–1) at 90 °C and 95% relative humidity. Based on the calculation result of activation energy, which was more than 0.4 eV (1.47 eV), it was determined that the proton conduction process for compound 1 was in accordance with the Vehicle mechanism. More interestingly, compound 1 was exploited as a catalyst to achieve the heterogeneous oxidative coupling of amines and realized a high yield (98.9%) toward N-benzylidenebenzylamine under ambient temperature and visible light irradiation (>400 nm) and O₂ atmosphere.
