Materials Data on HfTiF6 by Materials Project
HfTiF6 is alpha Rhenium trioxide-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Hf4+ is bonded to six equivalent F1- atoms to form HfF6 octahedra that share corners with six equivalent TiF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Hf–F bond lengths are 1.96 Å. Ti2+ is bonded to six equivalent F1- atoms to form TiF6 octahedra that share corners with six equivalent HfF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ti–F bond lengths are 1.93 Å. F1- is bonded in a linear geometry to one Hf4+ and one Ti2+ atom.
