Abstract

A case of organic-inorganic hybridized phosphotungstate modified by aromatic organophosphonic acid, K4Na4H11[KCo2(H2O)10P4W24O92{(PhPO)2]·48H2O (1), was successfully synthesized in conventional aqueous solution. The prominent structural feature is that the total structure of the [KP4W24O92{(PhPO)2]]23− resembles an V-shaped structure, which was stabilized by two [Co(H2O)5]2+ ions. Further, it can be connected into three-dimensional mesh structure by K+ ions. Surprisingly, 1 possesses a remarkably high proton conductivity of 1.59 × 10−2 S cm−1 at 95% RH, 318 K, probably due to its structure contains large amount of lattice water, coordination water and counter cations.

一种经苯基膦酸修饰的 Dawson- 型 {P4W24} 具有优异的质子传导性†。

在常规水溶液中成功合成了一例芳香族有机膦酸修饰的有机-无机杂化磷钨酸盐--K4Na4H11[KCo2(H2O)10P4W24O92{(PhPO)2]-48H2O (1)。其突出的结构特征是[KP4W24O92{(PhPO)2]]23-的整体结构类似于一个 V 型结构，由两个[Co(H2O)5]2+ 离子稳定。此外，它还可以通过 K+ 离子连接成三维网状结构。令人惊讶的是，1 在 95% RH、318 K 条件下具有 1.59 × 10-2 S cm-1 的惊人高质子电导率，这可能是由于其结构中含有大量的晶格水、配位水和反阳离子。
