资源简介：
The yttrium(III)-containing tungstoantimonate(III) [{Y(α-SbW9O31(OH)2)(CH3COO)(H2O)}3(WO4)]17− (1) has been synthesized in a simple one-pot reaction of Y3+ ions with [α-SbW9O33]9− and WO42− in a 3:3:1 molar ratio in 1 M LiOAc/AcOH buffer at pH 5.3. Polyanion 1 is composed of three (α-SbW9O33) units linked by three Y3+ ions and a capping, tetrahedral WO42− capping unit, resulting in an assembly with C3v symmetry. The hydrated ammonium-sodium salt of 1 was investigated in the solid state by single-crystal XRD, FT-IR spectroscopy, thermogravimetric and elemental analyses, and in solution by multinuclear NMR spectroscopy.
