Organometallic functionalized non-classical polyoxometalates: synthesis, characterization and electrochemical properties

摘要

Two monomeric non-classical tellurium-containing heteropolymolybdate-supported metal carbonyl derivatives (NH4)(5)H-3{[Te2Mo12(OH)O-44][Mn(CO)(3)]}center dot 18H(2)O (1) and (NH4)(8){[Te2Mo12(OH)O-44][ Re (CO)(3)]}center dot 13H(2)O (2) have been successfully isolated in good yields. Compounds 1 and 2 are the first two examples of metal carbonyl derivatives of heteromolybdate with tellurium as the central atom. These two compounds have been thoroughly characterized by single-crystal X-ray diffraction, elemental analyses, X-ray powder diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, and UV-Vis spectroscopy. The electrochemical catalytic activities of 1 and 2 including cyclic voltammetry and catalytic oxidation of nitrite have also been investigated.
