Tl2Te3 is alpha Pu-derived structured and crystallizes in the monoclinic C2/c space group. Tl(1) is bonded in a 3-coordinate geometry to one Te(2) and two equivalent Te(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 4-coordinate geometry to two equivalent Tl(1), one Te(1), and one Te(2) atom. In the second Te site, Te(2) is bonded in a distorted see-saw-like geometry to two equivalent Tl(1) and two equivalent Te(1) atoms.
Tl2Te3 is alpha Pu-derived structured and crystallizes in the monoclinic C2/c space group. Tl(1) is bonded in a 3-coordinate geometry to one Te(2) and two equivalent Te(1) atoms. The Tl(1)-Te(2) bond length is 3.43 Å. There is one shorter (3.44 Å) and one longer (3.54 Å) Tl(1)-Te(1) bond length. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 4-coordinate geometry to two equivalent Tl(1), one Te(1), and one Te(2) atom. The Te(1)-Te(1) bond length is 2.83 Å. The Te(1)-Te(2) bond length is 3.04 Å. In the second Te site, Te(2) is bonded in a distorted see-saw-like geometry to two equivalent Tl(1) and two equivalent Te(1) atoms.
