The structure described by BaTbF6 crystallizes in the orthorhombic Cmme space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent F(2) and eight equivalent F(1) atoms. Tb(1) is bonded in a 8-coordinate geometry to four equivalent F(1) and four equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one Tb(1) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to one Ba(1) and two equivalent Tb(1) atoms. is represented by the CIF file [CIF]
