| Description |
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.
