I.R. and 19F N.m.r. spectroscopy, molar conductance, magnetic moments and chemical analyses show that alkali oxytetrafluorovanadates(V), AI[VOF 4], are the principal products of the reactions of V2O5 with 40% HF and alkali bifluorides AIHF2 in presence of a small amount of alcohol at steam bath temperature. While the i.r. spectra suggest square pyramidal C4v structures for solid AI[VOF4], the 19F N.m.r. spectrum shows stereochemical non-rigidity owing to rapid fluorine rearrangement between C4v and the trigonal bipyramidal C2v stereochemistry of [VOF4]- in solution.
