Materials Data on Rb2TbF6 by Materials Project
Rb2TbF6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of Rb–F bond distances ranging from 2.90–3.39 Å. Tb4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Tb–F bond distances ranging from 2.26–2.35 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to two equivalent Rb1+ and two equivalent Tb4+ atoms. In the second F1- site, F1- is bonded in a 1-coordinate geometry to four equivalent Rb1+ and one Tb4+ atom. In the third F1- site, F1- is bonded in a 1-coordinate geometry to four equivalent Rb1+ and one Tb4+ atom.
