The structure described by CsTlF3 crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded in a 2-coordinate geometry to two equivalent F(2) and eight equivalent F(1) atoms. Tl(1) is bonded in a linear geometry to two equivalent F(2) and four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent Tl(1) atoms. In the second F site, F(2) is bonded in a distorted square co-planar geometry to two equivalent Cs(1) and two equivalent Tl(1) atoms. is represented by the CIF file [CIF]
