Materials Data on K2TlInI6 by Materials Project
(K)2TlInI6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight potassium molecules and one TlInI6 framework. In the TlInI6 framework, Tl1+ is bonded to six equivalent I1- atoms to form TlI6 octahedra that share corners with six equivalent InI6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Tl–I bond lengths are 3.31 Å. In3+ is bonded to six equivalent I1- atoms to form InI6 octahedra that share corners with six equivalent TlI6 octahedra. The corner-sharing octahedral tilt angles are 0°. All In–I bond lengths are 2.95 Å. I1- is bonded in a linear geometry to one Tl1+ and one In3+ atom.
