A closed hollow capsule structure assembled by double acetate-decorated Anderson-like polyanions
An inorganic-organic hybrid vanadotungstate, Na 6 [VW 6 O 22 (CH 3 COO) 3 ]·11H 2 O (1), was synthesized in aqueous solution and characterized by infrared spectrum, elemental analysis, thermogravimetric analysis, X-ray photoelectron spectroscopy, and single-crystal X-ray diffraction. The result of t...

The result of the single-crystal X-ray diffraction analysis reveals that the polyanion of 1 is an acetate single-sided decorated Anderson-like polyoxotungstate with a V

are linked by six sodium cations on the same plane to form a closed hollow capsule structure with the inner major axis of 8.54 Å and minor axis of 3.11 Å. As basic building blocks, the closed hollow capsule moieties are assembled into 1D chain-like structures through direct Na−O bonds without additional linkers. The electrochemical behavior of 1 was investigated in pH 4.8 buffer solution to investigate its potential application in electrochemical catalysis; 1 has good catalytic activity for oxidation of thioanisole. |
