Tl Tl Te Au
AuTl2Te is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AuTl2Te clusters. Au(1) is bonded in a 3-coordinate geometry to two equivalent Tl(1) and one Te(1) atom. Both Au(1)-Tl(1) bond lengths are 2.48 Å. The Au(1)-Te(1) bond length is 1.96 Å. Tl(1) is bonded in a 3-coordinate geometry to one Au(1), one Tl(1), and one Te(1) atom. The Tl(1)-Tl(1) bond length is 1.96 Å. The Tl(1)-Te(1) bond length is 2.48 Å. Te(1) is bonded in a 3-coordinate geometry to one Au(1) and two equivalent Tl(1) atoms.
