Abstract

The solvatothermal reactions of V₂O₅, the appropriate organoamine and HF in the temperature range 100-180 °C yielded a series of vanadium fluorides and oxyfluorides. The compounds [NH₄][H₃N(CH₂)₂NH₃][VF₆] (1) and [H₃N(CH₂)₂NH₃][VF₅(H₂O)] (2) contain mononuclear V(III) anions, while [H₃N(CH₂)₂NH₂(CH₂)₂NH₃]₂ [VF₅(H₂O)]₂[VOF₄(H₂O)] (3) exhibits both V(IV) and V(III) mononuclear anions. Both compound 4, [H₃NCH₂(C₆H₄)CH₂NH₃][VOF₄]·H₂O (4·H₂O) and compound 5, [HN(C₂H₄)₃NH][V₂O₂F₆ (H₂O)₂] (5) contain binuclear anions constructed from edge-sharing V(IV) octahedra. In contrast, [H₃N(CH₂)₂NH₂(CH₂)₂NH₃]₂[V₄O₄F₁₄(H₂O)₂], (6) exhibits a tetranuclear unit of edge- and corner-sharing V(IV) octahedra. Compound 7, [H₃N(CH₂)₂NH₂][VF₅], contains chains of corner-sharing {V^IVF₆} octahedra, while [H₂N(C₂H₄)₂NH₂]₃[V₄F₁₇O]·1.5H₂O (8·1.5H₂O) is two-dimensional with a layer of V(III) and V(IV) octahedra in an edge- and corner-sharing arrangement. In the case of [H₃N(CH₂)₂NH₃][V₂O₆] (9), there was no fluoride incorporation, and the {V₂ O₆}_n^{2 n -} anion is a one-dimensional chain of corner-sharing V(V) tetrahedra.
