    Description / Table of Contents: When during the electrolytic reduction of a solution of V2O5 in hydrofluoric acid the oxidation state of the vanadium has become +2.5, V2F5 · 7 H2O precipitates. As its powder pattern shows, it is isotypic with Fe2F5 · 7 H2O. By heating in vacuo it is dehydrated to V2F5. - The compounds (NH4)2VF4 · 2 H2O and KVF3 together with some KF can be obtained from a solution of VCl2 · 4 H2O in water. By reaction of VCl2 · 2 CH3OH with liquid (HF)x a VF2 is formed, to which at least 0.2 HF are bound. The magnetic susceptibilities of the compounds were measured.
    Notes: Wird in Flußsäure gelöstes V2O5 elektrolytisch reduziert, so fällt aus genügend konzentrierten Lösungen beim Erreichen der Oxydationsstufe +2,5 des Vanadins V2F5 · 7 H2O aus, das sich zu V2F5 entwässern läßt. Nach seinem Debyeogramm ist V2F5 · 7 H2O isotyp dem Fe2F5 · 7 H2O. Aus wäßriger Lösung von VCl2 · 4. H2O lassen sich (NH4)2VF4 · 2 H2O und ein KVF3 darstellen, das nicht frei von KF zu erhalten ist. Bei der Umsetzung von VCl2 · 2 CH3OH mit kondensiertem Fluorwasserstoff entsteht ein VF2, das noch mindestens 0,2 HF gebunden hält. Die magnetischen Suszeptibilitäten der Verbindungen wurden gemessen.
