Isolation and characterization of a new polyoxometalate ligand, H3SbW14O5010−, and its interactions with f-elements.

We report the synthesis and characterization (Raman, FTIR, DLS, single crystal XRD) of Cs₁₀H₃SbW₁₄O₅₀·6H₂O, which contains a new polyoxometalate building block: H₃SbW₁₄O₅₀¹⁰⁻ (SbW₁₄). Solution-state fluorescence, DLS, and UV-vis absorbance results with Nd³⁺, Eu³⁺, Am³⁺, and Cm³⁺ confirm that SbW₁₄ acts as an efficient complexant and fluorescence sensitizer for f-elements.
