Abstract

A new anion conductive oxyfluoride Bi2VO5F0.7 has been obtained. Its crystal structure, related to the well-known Aurivillius phases, has been determined from powder X-ray and neutron diffraction data combined with a piezo test and magnetic measurements (I4mm, a = 3.869(3) Angstrom, c = 15.648(6) Angstrom, R-p = 4.41, R-wp = 9.50%). The transport properties of this compound have been studied as a function of temperature by impedance spectroscopy. The relation of the Bi2VO5F0.7 crystal structure and anion conductivity with different modifications of Bi2VO5.5 oxide is discussed.
