Actinide complexes with Wells-Dawson Polyoxometalates (Part 1): Americium and Curium

Abstract

We report the first trivalent actinide complexes with a Wells-Dawson polyoxometalate. Americium(III) forms two distinct phases: triclinic K17Am(P2W17O61)2•42.5H2O and monoclinic K17Am(P2W17O61)2•12H2O. Curium(III) crystallizes as monoclinic K17Cm(P2W17O61)2•8H2O. XRD-quality single crystals were obtained from just ~330 nanograms of actinides. This work establishes clear structure-property relationships that will guide investigations on scarce f-elements.
