Abstract:
A novel Ru(III)-containing tungstoantimonate Na16H22[(B-β-SbW9O33)6(W3RuO7)2(W4O11)]·118H2O (1) hexamer was successfully synthesized using the hydrothermal synthesis method. Analysis by single-crystal X-ray diffraction revealed that the polyanion comprises six trivacant Keggin-type [B-β-SbW9O33]9- units interconnected by six {WO6} and six Ru/W disorder octahedra, resulting in an intriguing cyclohexane boat-like conformation. Compound 1 exhibits favorable proton conductivity, with a measured conductivity (σ) of 5.41 × 10-3 S cm-1 at 333 K and 55% relative humidity (RH). The activation energy (Ea) of compound 1 was determined to be 0.40 eV, providing evidence that its proton conductivity conforms to the Grotthus mechanism.
