Materials Data on Tl4Te3Pb by Materials Project
Tl4PbTe3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. Tl1+ is bonded in a 5-coordinate geometry to five Te2- atoms. There are a spread of Tl–Te bond distances ranging from 3.22–3.65 Å. Pb2+ is bonded to six Te2- atoms to form corner-sharing PbTe6 octahedra. The corner-sharing octahedra tilt angles range from 0–38°. There are four shorter (3.36 Å) and two longer (3.38 Å) Pb–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 8-coordinate geometry to six equivalent Tl1+ and two equivalent Pb2+ atoms. In the second Te2- site, Te2- is bonded in a 10-coordinate geometry to eight equivalent Tl1+ and two equivalent Pb2+ atoms.
