Materials Data on UF6 by Materials Project

Abstract

UF6 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four uranium hexafluoride molecules. U6+ is bonded in an octahedral geometry to six F1- atoms. There are five shorter (2.02 Å) and one longer (2.03 Å) U–F bond lengths. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one U6+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one U6+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one U6+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one U6+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one U6+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one U6+ atom.
