Abstract
A new hybrid constructed from Wells–Dawson polyanions and silver complexes, [Ag(bipy)] 2[Ag(bipy)(Hbipy)][P 2W 18O 62]·[H 2bipy] ( 1) (bipy = 4,4′-bipyridine), has been hydrothermally synthesized, and characterized by IR, TG, XRPD and single-crystal X-ray diffraction. Structural analysis reveals that compound 1 possesses left- and right-helical chains constructed by Ag(bipy) complexes. Furthermore, these helical chains are linked together by Ag atoms via sharing O atoms of the Wells–Dawson polyanions to form two-dimensional (2D) sheets. Finally, a 3D framework is obtained with (4 1·6 4·8 1)(4 6·6 2·8 2·10 5) topology, which is constructed by the 2D sheets through the O atoms of the Wells–Dawson polyanions. Also, the electrochemical behavior and electrocatalysis of 1 modified carbon paste electrode ( 1-CPE) have been studied in detail. The results indicate that 1-CPE has remarkable stability and good electrocatalytic activities.
