Materials Data on Tl2TeCl6 by Materials Project
Tl2TeCl6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Tl1+ is bonded to twelve equivalent Cl1- atoms to form TlCl12 cuboctahedra that share corners with twelve equivalent TlCl12 cuboctahedra, faces with six equivalent TlCl12 cuboctahedra, and faces with four equivalent TeCl6 octahedra. All Tl–Cl bond lengths are 3.67 Å. Te4+ is bonded to six equivalent Cl1- atoms to form TeCl6 octahedra that share faces with eight equivalent TlCl12 cuboctahedra. All Te–Cl bond lengths are 2.56 Å. Cl1- is bonded in a distorted single-bond geometry to four equivalent Tl1+ and one Te4+ atom.
