Hydroxylammonium Tetrafluoridooxidovanadate(V) - (NH3OH)[VOF4]

摘要

Hydroxylammonium tetrafluoridooxidovanadate(V) has been prepared by reaction of (NH3OH)Cl and VOF3 in anhydrous HT solvent and characterised in the solid state by single-crystal X-ray diffraction and Raman spectroscopy. Colourless (NH3OH)[VOF4] crystallises in the monoclinic space group P2(1) with a = 7.2349(2) angstrom, b = 5.0351(2) angstrom, c = 12.8322(4) angstrom, beta = 94.843(3)degrees, V = 465.79(3) angstrom(3) and Z = 4 at 150 K. The crystal structure of the title compound is comprised of polymeric chain anions, [VOF4](n)(n-), interconnected by hydrogen bonds with hydroxylammonium cations, (NH3OH)(+).
