Materials Data on K2TlInCl6 by Materials Project

Abstract

K2TlInCl6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. K1+ is bonded to twelve equivalent Cl1- atoms to form distorted KCl12 cuboctahedra that share corners with twelve equivalent KCl12 cuboctahedra, faces with six equivalent KCl12 cuboctahedra, faces with four equivalent TlCl6 octahedra, and faces with four equivalent InCl6 octahedra. All K–Cl bond lengths are 3.94 Å. Tl1+ is bonded to six equivalent Cl1- atoms to form TlCl6 octahedra that share corners with six equivalent InCl6 octahedra and faces with eight equivalent KCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Tl–Cl bond lengths are 3.02 Å. In3+ is bonded to six equivalent Cl1- atoms to form InCl6 octahedra that share corners with six equivalent TlCl6 octahedra and faces with eight equivalent KCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All In–Cl bond lengths are 2.54 Å. Cl1- is bonded in a linear geometry to four equivalent K1+, one Tl1+, and one In3+ atom.
