Abstract: Potassium α-and β-trivanadoenneatungstogermanates were prepared and characterized by means of elemental analysis, IR, 51V and 183W NMRspectra and polarography. The single crystal structure of a-isomer was determined. The final Ris 0.083. The results show that two prepared heteropoly anions have Keggin structure, and a-isomer belongs to A-type and has stronger oxidizing ability than β-isomer.

Key words: Crystal structure, Trisubstituted compound, Tungstogermanate
