A {Ru(C<sub>6</sub>H<sub>6</sub>)}-Containing Isopolymolybdate with Good Photocatalytic Activity for Oxidative Coupling of Amines, and Proton Conduction Properties

The crystallographic characterization of compound <b>1</b> revealed that it contains an unusual {Mo<sub>24</sub>O<sub>86</sub>} cluster together with six {Ru(C<sub>6</sub>H<sub>6</sub>)} groups, having the largest number of {Ru(C<sub>6</sub>H<sub>6</sub>)} groups within the field of {Ru(C<sub>6</sub>H<sub>6</sub>)}-containing polyoxometalates.

Abstract

We present a nonclassical {Ru(C<sub>6</sub>H<sub>6</sub>)}-containing isopolymolybdate Cs<sub>8</sub>K<sub>2</sub>Na<sub>2</sub>H<sub>4</sub>{[(C<sub>6</sub>H<sub>6</sub>)Ru]<sub>6</sub>Mo<sub>24</sub>O<sub>86</sub>}·35H<sub>2</sub>O (<b>1</b>) via one-pot reaction. The crystallographic characterization of compound <b>1</b> revealed that it contains an unusual {Mo<sub>24</sub>O<sub>86</sub>} cluster together with six {Ru(C<sub>6</sub>H<sub>6</sub>)} groups, having the largest number of {Ru(C<sub>6</sub>H<sub>6</sub>)} groups within the field of {Ru(C<sub>6</sub>H<sub>6</sub>)}-containing polyoxometalates. Results showed that compound <b>1</b> displayed excellent proton conductivity (9.8 × 10<sup>-3</sup> S cm<sup>-1</sup>) 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 <b>1</b> was in accordance with the Vehicle mechanism. More interestingly, compound <b>1</b> 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 O<sub>2</sub> atmosphere.
