title: Tetragonal CeNbO(4) at 1073 K in air and in vacuo.
abstract: The structure of the high-temperature scheelite-type polymorph of cerium niobium tetraoxide, CeNbO(4), has been determined using time-of-flight neutron powder diffraction data collected both in situ at 1073 K in air and in vacuo. In both cases, the structure was found to be tetragonal, with I4(1)/a symmetry and without any significant deviation from the stoichiometric composition.
