The compound described by CdTbF6 crystallizes in the tetragonal P4_2/m space group. Tb(1) is bonded in a 8-coordinate geometry to four equivalent F(1) and four equivalent F(2) atoms. Cd(1) is bonded in an octahedral geometry to two equivalent F(1) and four equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a bent 150 degrees geometry to one Tb(1) and one Cd(1) atom. In the second F site, F(1) is bonded in a trigonal planar geometry to two equivalent Tb(1) and one Cd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
