    Description / Table of Contents: Es wird über die Darstellung der Monooxopentafluorovanadate(V) MI2VOF5 von Kalium, Ammonium und Åthylendiamin sowie der Monooxotetrafluorovanadate(V) MIVOF4 von Natrium, Pyridin, α Picolin, Chinolin, Guanidin, Äthylendiamin, α,α′-Dipyridyl und o-Phenanthrolin berichtet. Die Tetrafluoroverbindungen des Natriums, Chinolins und α,α′-Dipyridyl wurden IE-spektroskopisch charakterisiert (700-4000 cm-1), und bei (py · H)VOF4, (Chinolin · H)VOP4 und (α,α′-Dipyridyl · H2) (VOF4)2 wurde thermogravimetrisch unreines V2O5 als Endprodukt der thermischen Zersetzung an Luft beobachtet.
    Notes: The preparation of potassium, ammonium and ethylenediamine monooxopentafluorovanadates and of pyridine, α-picoline, quinoline, guanidine, ethylenediamine, α,α′-dipyridyl, o-phenanthroline and sodium monooxotetrafluorovanadates are reported. Infrared spectra of NaVOF4 · 0.7 HaO, (quinoline · H)(VOF4) and (α-α′-dipyridyl · H2) (VOF4)2 have been recorded (700-4000 cm-1). Thermogravimetric study up to 450°C of (pyridine · H)(VOF4), (quinoline H)(VOF4) and (α,α′-dipyridyl · H2)(VOP4)2 show that in all cases impure V2O5 is the ultimate product on heating.
