Xenon Hexafluoride: Structure of a Cubic Phase at -80°C

Abstract
The crystal structure of a cubic phase of composition XeF 6 has been determined at -80°C. There are no simple molecules in the complex structure which involves 1008 atoms distributed over 1600 positions per unit cell. Ions of XeF 5 + and F- are associated in tetrameric and hexameric rings of point group symmetries 4̅ and 32, respectively. The structure contains right-and left-handed conformations of both tetramers and hexamers. The handedness of the tetramers is disordered but the orientation is ordered. The handedness of the hexamers is ordered but the orientation is disordered.
