Tl9LaTe6 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. La3+ is bonded to six Te2- atoms to form LaTe6 octahedra that share corners with six equivalent TlTe6 octahedra. The corner-sharing octahedra tilt angles range from 0–39°. There are two shorter (3.25 Å) and four longer (3.28 Å) La–Te bond lengths. There are two inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 5-coordinate geometry to five Te2- atoms. There are a spread of Tl–Te bond distances ranging from 3.26–3.72 Å. In the second Tl1+ site, Tl1+ is bonded to six Te2- atoms to form TlTe6 octahedra that share corners with six equivalent LaTe6 octahedra. The corner-sharing octahedra tilt angles range from 0–39°. There are four shorter (3.51 Å) and two longer (3.56 Å) Tl–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 8-coordinate geometry to one La3+ and seven Tl1+ atoms. In the second Te2- site, Te2- is bonded in a 1-coordinate geometry to one La3+ and nine Tl1+ atoms.
