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.We report the synthesis and characterization (Raman, FTIR, DLS, single crystal XRD) of Cs10H3SbW14O50·6H2O, which contains a new polyoxometalate building block: H3SbW14O5010- (SbW14).
