Abstract
Chromium(VI) oxide undergoes a very facile reduction with formaldehyde solution in the presence of 40% hydrofluoric acid and AF (A = NH4 +, Na+, K+ or Rb+) giving green, crystalline A2[CrF5(H2O)-] in very high yields. The structural assessment of the compounds was made from magnetic moments, infrared and electronic spectroscopic data. The electronic spectra of A2[CrF5(H2O)-] in the solid state and in solution suggest no apparent change in its structure.Keywords
