The material structure described by Rb2TbF6 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent F(1), four equivalent F(2), and four equivalent F(3) atoms. Tb(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and two equivalent Tb(1) atoms. In the second F site, F(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Tb(1) atom. In the third F site, F(3) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Tb(1) atom. is represented by the CIF file [CIF]
