Preparation and Properties of a Copper Niobium Oxyfluoride.
Abstract
A fluorinated phase of copper niobium oxide with the formula CuNb2O5.3FO7 has been synthesized. The oxyfluoride displays orthorhombic symmetry with a = 9.665(5), b = 10.40(3), and c = 7.85(3) angstrom. Magnetic susceptibility data indicates a Curie Weiss behavior consistent with the quantity of Cu(2+) (d to the 9th power) present. The measured room temperature resistivity is 0.5 omega-cm and the electronic activation energy of 0.06 eV indicates some electron delocalization. (Author)
