Аннотация

Citrate complexes of niobium(V) formed in the interaction of [Nb ₆ O ₁₉ ] ⁸⁻ hexaniobate with citric acid are used for transferring the {NbO} ³⁺ niobium group to the pseudo-trilacunary [α-B-As ^III W ₉ O ₃₃ ] ⁹⁻ anion with the formation of sandwich-type [(AsW ₉ O ₃₃ ) ₂ (NbO) ₃ (H ₂ O)] ⁹⁻ complexes. Slow evaporation of the reaction mixture in the presence of dimethylammonium chloride yields crystalline product (NMe ₂ H ₂ ) ₉ [(AsW ₉ O ₃₃ ) ₂ (NbO) ₃ (H ₂ O)]·44H ₂ O (1) whose structure is determined by single crystal XRD. When the (NBu ₄ ) ⁺ salt (obtained by the exchange reaction between 1 and tetrabutylammonium bromide) of [(AsW ₉ O ₃₃ ) ₂ (NbO) ₃ (H ₂ O)] ⁹⁻ is dissolved in DMF, As ³⁺ is oxidized to As ⁵⁺ with the formation of a mixture of the Keggin-type [AsW ₁₁ NbO ₄₀ ] ⁴⁻ and [AsW ₁₀ Nb ₂ O ₄₀ ] ⁵⁻ anions. In an aqueous solution 1 is oxidized by hydrogen peroxide with the formation of a mixture of Keggin anions with different numbers of niobium atoms in the structure.
