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

Key Points

• The aim is to explore the formation of trivalent actinide complexes with Wells-Dawson polyoxometalates.
• Synthesis of americium and curium complexes with Wells-Dawson polyoxometalates.
• Characterization of the produced complexes using X-ray diffraction (XRD).
• Crystallization under controlled conditions to obtain single crystals.
• Americium(III) forms two distinct phases: K17Am(P2W17O61)2•42.5H2O and K17Am(P2W17O61)2•12H2O.
• Curium(III) crystallizes as K17Cm(P2W17O61)2•8H2O.
• New structural information on actinide polyoxometalate complexes is provided.
