Reconstructed Synthetic and Characterization of a Insoluble Polyoxometalate Coordination Polymer

A general reconstructed synthetic strategy for ionic liquids-supported the insoluble polyoxometalate coordination polymer was proposed. A insoluble polyoxometalate(POMs) coordination polymer 1, [{La(H2O)5(dipic)}{La(H2O)(dipic)}]2{Mo8O26}·10H2O was successfully reconstructed by electrolyzing in ionic liquids on conducting glasses coated with indium tin oxide(ITO) electrode. The polyoxometalate coordination polymer is insoluble in aqueous solution and usual organic solutions, but soluble in the ionic liquid [RMIM][HT] or [RMIM][HP]. The reconstructed synthetic polyoxometalate coordination polymer was characterized via XPS and XRD techniques. The result show the XRD pattern of the deposited POMs on ITO electrode has the same crystal structure as the polyoxometalate coordination polymer 1, which imply that the crystal structure of the deposited POMs on ITO electrode keeps the same as the original POMs compound. It was favored the compound 1 reconstructed by the electrolyzing in an ionic liquid.
