Abstract
A case of organic-inorganic hybridized phosphotungstate modified using aromatic organophosphonic acid, K<sub>4</sub>Na<sub>4</sub>H<sub>11</sub>[KCo<sub>2</sub>(H<sub>2</sub>O)<sub>10</sub>P<sub>4</sub>W<sub>24</sub>O<sub>92</sub>{(PhPO)<sub>2</sub>}]·48H<sub>2</sub>O (1), was successfully synthesized in conventional aqueous solution. The prominent structural feature is that the total structure of [KP<sub>4</sub>W<sub>24</sub>O<sub>92</sub>{(PhPO)<sub>2</sub>}]<sup>23-</sup> resembles a V-shaped structure, which was stabilized by two [Co(H<sub>2</sub>O)<sub>5</sub>]<sup>2+</sup> ions. Furthermore, it can be connected into a three-dimensional mesh structure using K<sup>+</sup> ions. Surprisingly, 1 possesses a remarkably high proton conductivity of 1.59 × 10<sup>-2</sup> S cm<sup>-1</sup> at 95% RH and 318 K probably due to the fact that its structure contains large amounts of lattice water molecules, coordination water molecules and counter cations.
