Аннотация

This research summarizes the behavior [Mn(Nb₆O₁₉)₂]¹²⁻ and [(Nb₆O₁₉)₂(Pt(OH)₂)₂]¹²⁻ in basic solutions at pH 12. After heating of [Mn(Nb₆O₁₉)₂]¹²⁻ for 20 min at 60° in the presence of NaOH new very unstable phase Na₈[Nb₆O₁₉]·25H₂O (1) was obtained. Gentle (60 °C) heating of a solution of [(Nb₆O₁₉)₂(Pt(OH)₂)₂]¹²⁻ for 10 min in the presence of NaOH causes rearrangement into [Pt(Nb₆O₁₉)₂]¹²⁻, which was isolated as Na₁₂[Pt(Nb₆O₁₉)₂]·52H₂O (2). Longer heating yields white insoluble amorphous precipitate and crystals of a new hexaniobate phase K₅Na₃[Nb₆O₁₉]·9H₂O (3). Crystal structures of the products and their structural relationship with known analogs are discussed.
