Abstract
- Two new cadmium-containing Wells-Dawson polyoxometalates K8[α1-P2W17Cd(H2O)O61]⋅14H2O (α1-P2W17Cd) and K8[α2-P2W17Cd(H2O)- O61]⋅16H2O (α2-P2W17Cd) were synthesized as water-soluble potassium salts. The cadmium-substituted complexes were characterized by IR, 31P-NMR, 1113Cd-NMR spectroscopy and cyclic voltammetry (CV). Redox activities for the tungsten and cadmium centers were observed by cyclic voltammetry. It was found that the presence of cadmium decreased the electrocatalytic activity of the [α1-LiP2W17O61] and α2-[P2W17O61]10- heteropolyanions. [ABSTRACT FROM AUTHOR]
