Tl2SnTe5 crystallizes in the tetragonal I4/mcm space group. The structure consists of four 7440-28-0 atoms inside a TlSnTe5 framework. In the TlSnTe5 framework, Tl(2) is bonded in a 8-coordinate geometry to eight equivalent Te(2) atoms. Sn(1) is bonded in a tetrahedral geometry to four equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a square co-planar geometry to four equivalent Te(2) atoms. In the second Te site, Te(2) is bonded in a 1-coordinate geometry to two equivalent Tl(2), one Sn(1), and one Te(1) atom.
