Abstract 

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
