On the Structure of Gaseous XeF6

The Xenon-Fluorine System

“…Since this analysis was completed two reports of electron diffraction studies with XeFe vapor have been published. [34][35][36] Although the complete structure of XeFe has not been determined, both authors rule out a highly symmetrical structure for XeF6, w'hich result agrees with the tentative conclusion we had drawn from the equilibrium constant data.…”

The structure of xenon hexafluoride in the solid state

“…Early electron diffraction and vibrational spectroscopical data clearly rule out a rigid octahedral structure [1][2][3][4]. However, a C 3v distorted octahedral structure is in agreement with most physical data.…”

Electron Diffraction Study of Rhenium Fluorides. II. Structure, Pseudorotation, and Anharmonic Coupling of Modes in ReF7

“…The characteristic feature of the experimental FaF. radial distribution is a strong skewing of the peak, much like that observed for geminal FF distances in XeF s .18, 19 An adequate representation of the experimental curve can be obtained by retaining the distribution of FaF. distances generated by a deformation along the e2" coordinate, which is symmetrical about the D5h reference value, and assigning vibrational amplitudes which increase rapidly with increasing internuclear distance.…”
