Title: Materials Data on K2UF6 by Materials Project

Abstract

K2UF6 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are three shorter (2.65 Å) and six longer (2.89 Å) K–F bond lengths. U4+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are three shorter (2.27 Å) and six longer (2.40 Å) U–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded to two equivalent K1+ and two equivalent U4+ atoms to form a mixture of corner and edge-sharing FK2U2 tetrahedra. In the second F1- site, F1- is bonded in a 1-coordinate geometry to four equivalent K1+ and one U4+ atom.
