Abstract: Polyvanadates [BdaH₂](VO₃)₂ (A), [BdaH₂]₃V₁₀O₂₈. 6H₂O (B), and [BdaH₂]₂H₂V₁₀O₂₈. 4H₂O (C) were synthesized from the system V₂O₅-1,4-butanediammonium (Bda)-H₂O-(HCl). Syntheses variables were: mole ratio n(V): n(Bda), concentration of V, pH of the solution, and reaction temperature. Compounds were characterized by S-ray powder diffraction and IR spectra. The thermal decomposition in air was also studied. As the intermediate reaction product of the compound C was determined nonaqueous dihydrogendecavanadate [BdaH₂]₂H₂V₁₀O₂₈ (D). V₂O₅ was the final reaction product of all compounds.
