Synthesis,structure,and electrochemical properties of a sandwich-type{Co6}-cluster-added germanotungstate
A new sandwich-type{Co6}-added polyoxotungstate,[Co(dien)2]{[Co(dien)(H2O)]2[Co(dien)]2[Co6(en)2(μ3-OH)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,pow-der 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.
