New oxyfluorotellurates(IV): MTeO₃F (M = Fe^III, Ga^III and Cr^III)

J. P. Laval, N. Jennene Boukharrata and P. Thomas

Abstract: The crystal structures of the new isomorphous compounds iron(III) oxyfluorotellurate(IV), FeTeO₃F, gallium(III) oxyfluorotellurate(IV), GaTeO₃F, and chromium(III) oxyfluorotellurate(IV), CrTeO₃F, consist of zigzag chains of MO₄F₂ distorted octahedra alternately sharing O-O and F-F edges and connected via TeO₃ trigonal pyramids. A full O/F anionic ordering is observed and the electronic lone pair of the Te^IV cation is stereochemically active.

Formula: FeTeO₃F and GaTeO₃F
