Abstract

A new sandwich-type {Co₆}-added polyoxotungstate, [Co(dien)₂]{[Co(dien)(H₂O)]₂[Co(dien)]₂[Co₆(en)₂(μ₃OH)₂(H₂O)₆(GeW₈O₃₁)₂]}·5.5H₂O (1), where dien=diethylenetriamine and en=ethylenediamine, was synthesized via hydrothermal reaction. The polyoxoanion of compound 1 was constructed by a belt-like {Co₆} cluster core sandwiched by two {GeW₈} units. 1 was characterized by single crystal X-ray diffraction, element analysis, IR spectroscopy, powder X-ray diffraction (PXRD), and thermogravimetric analysis (TGA) experiments, respectively. The electrochemical properties of 1 were explored by the cyclic voltammetry (CV) technique, and 1 exhibited excellent electrocatalytic activity in nitrite reduction. CCDC: 2270995.
