Abstract
Two oxoperoxofluoro complexes of vanadium, viz., (NH 4) 2 [VO(O 2) (OH)F 2] and K 4 [V 2O 3(O 2) 2F 4] have been prepared by crystallising solutions of vanadium pentoxide in aqueous hydrofluoric acid with ammonium or potassium fluoride solutions containing hydrogen peroxide at 5°C. The orange crystalline substances are quite stable. They are very weakly paramagnetic and display strong ν(VO) and ν(OO) bands in their i.r. spectra. The TGA curves of the complexes show horizontals corresponding to the formation of (NH 4) 4 [V 2O 5F 4] and K 4[V 2O 5F 4] respectively which have actually been isolated. These appear to be oxobridged complexes. The x-ray patterns of the two peroxo complexes are distinctly different.
