An Organic-Inorganic Hybrid Based on Keggin-Type Polyoxometalate and Hypoxanthine: Synthesis, Structure, Stability, and Electrochemistry Properties

摘要

The organic-inorganic hybrid H-5[Ag-2(hyp)(2)](2)[BW12O40]center dot 9H(2)O (1) (hpy = hypoxanthine), based on Keggin-type polyoxometalate and hypoxanthine, was prepared by hydrothermal synthesis and characterized by single-crystal and powder X-ray diffraction, IR spectroscopy, elemental analysis, and thermogravimetry. The title compound has a two-dimensional layer structure constructed by Keggin-type [BW12O40](5-) anion, silver, and the biomolecule hyp. In addition, compound 1 exhibited excellent stability and superior activity in the electro-catalytic oxidation of glucose.
