Facile Incorporation of Platinum(IV) into Polyoxometalate Frameworks: Preparation of [H2PtIVV9O28]5− and Characterization by 195Pt NMR Spectroscopy

A new mate for vanadate: The platinum(IV)-containing polyoxovanadate [H2PtIVV9O28]5− (1) has been synthesized and structurally characterized (see polyhedral representation). The characterization of polyanion 1 in solution by 195Pt NMR spectroscopy is unprecedented in POM chemistry. The facile synthetic procedure with the PtIV precursor H2Pt(OH)6 appears to be a convenient and general methodology for making a large variety of PtIV-containing polyoxometalates.
