Preparation and characterization of NH4Bi3F10
Published online by Cambridge University Press: 31 January 2011
Abstract
A new NH4Bi3F10 compound was prepared, which results from a reaction between Bi2O3 and NH4F in an argon stationary atmosphere. It has a cubic fluorite-related structure isotypic with KBi3F10 with space group Fm3m (a = 11.974 Å). Further heating leads to decomposition to BiF3. IR spectra at different temperatures show the disappearance of NH4 group characteristic vibrations. Indexed x-ray diffraction pattern and IR spectra at different decomposition temperatures are given.
