Study synthesizes rare-earth selenates, revealing their complex structures and properties.
Three rare-earth selenates, namely, poly[diaquadi-μ-selenato-μ-selenito-diytterbium], [Yb 2 (SeO 3 )(SeO 4 ) 2 (H 2 O) 2 ] n , poly[μ-(hydrogen selenito)-μ-selenato-ytterbium], [Yb(HSeO 3 )(SeO 4 )] n , and poly[[tetraaquatri-μ-selenato-dithulium] monohydrate], {[Tm 2 (SeO 4 ) 3 (H 2 O) 4 ]·H 2 O} n , were synthesized by hydrothermal methods. Single-crystal X-ray diffraction (SCXRD) analysis shows that all three compounds form three-dimensional framework structures constructed from interconnected LnO x polyhedra (Ln = Yb, Tm; x = 7–8) and selenate (SeO 4 2− ) and/or selenite (SeO 3 2− ) groups. Their compositions were further supported by scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX), and their oxidation states were assessed by bond-valence-sum (BVS) calculations.
