Abstract
A new POM-templated metal–organic complex [Cu4(L)7(H2O)12(SiMo12O40)2]·7H2O [L = N,N′-bis(3-pyridinecarboxamide)-1,6-hexane], has been hydrothermally synthesized and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction analysis. The results reveal that the complex is a 2D metal–organic coordination framework of [Cu4(L)7(H2O)12]n8n+ cations containing decanuclear cycles with dimensions of ca. 17.55 × 57.42 A, in which the SiMo12O404− anions act as non-coordinated anionic templates. The electrochemical properties of a bulk-modified carbon paste electrode of the complex have been investigated, and the results indicate that the complex-modified CPE has good electrocatalytic activity toward the reduction of nitrite in aqueous 1 M H2SO4 solution.
