One-Dimensional Zr-Substituted Phosphotungstate with Proton Conductivity
A one-dimensional chainlike Zr-substituted phosphotungstate {[NH<sub>2</sub>(CH<sub>3</sub>)<sub>2</sub>]<sub>8</sub>H<sub>6</sub>[(Zr<sub>2</sub>O<sub>4</sub>)P<sub>2</sub>W<sub>16</sub>O<sub>60</sub>]·10H<sub>2</sub>O}<sub><i>n</i></sub> (<b>1</b>), was synthesized via a conventional aqueous solution method, employing the hexavacant Dawson-type precursor [H<sub>2</sub>P<sub>2</sub>W<sub>12</sub>O<sub>48</sub>]<sup>12-</sup>. Compound <b>1</b> features a rare divacant [P<sub>2</sub>W<sub>16</sub>O<sub>60</sub>]<sup>14-</sup> building unit, interconnected into a one-dimensional sinusoidal chain structure through the {Zr<sub>2</sub>O<sub>4</sub>} connectors. This compound demonstrates excellent proton conductivity, achieving a high conductivity of 5.30 × 10<sup>-3</sup> S·cm<sup>-1</sup> at 348 K.
