Y-, Sm-, and Er-Containing Heteropoly Tungstates With Peacock–Weakley Anion: Synthesis, Structure, and Surface Micromorphology

The conditions for the synthesis of novel sodium heteropoly decatungstometalates (III) – Na9[Y(W5O18)2]·35H2O, Na7.5Н1.5[Sm(W5O18)2]·39.5H2O, Na9[Er(W5O18)2]·32H2O from the aqueous solution of sodium tungstate acidified to Z=0.80 with a ratio ν(X):ν(W)=1:10 and with acetone admixture were elaborated. Isolated salts were analyzed using Single Crystal X-ray Diffraction Analysis, FTIR and Raman spectroscopy, Scanning Electron Microscopy

Pr-, Nd-, and Eu-Containing Heteropoly Tungstates With Peacock–Weakley Anion: Synthesis From Aqueous-Acetone Media, FT-IR Spectroscopy, and Surface Micromorphology

The conditions for the synthesis of pure inorganic sodium heteropoly decatungstometalates (III) – Na9[Pr(W5O18)2]∙34.25H2O, Na9[Nd(W5O18)2]·34H2O, and Na9[Eu(W5O18)2]·34H2O, from the aqueous solution of sodium tungstate acidified to Z=0.80 with a ratio ν(Ln):ν(W)=1:10 and with acetone admixture were established. Isolated salts were analyzed using Elemental Analysis, FT-IR spectroscopy, and Scanning ElectronMicroscopy
