Materials Data on K2YTlBr6 by Materials Project
(K)2YTlBr6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight potassium molecules and one YTlBr6 framework. In the YTlBr6 framework, Y3+ is bonded to six equivalent Br1- atoms to form YBr6 octahedra that share corners with six equivalent TlBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Y–Br bond lengths are 2.79 Å. Tl1+ is bonded to six equivalent Br1- atoms to form TlBr6 octahedra that share corners with six equivalent YBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Tl–Br bond lengths are 3.18 Å. Br1- is bonded in a linear geometry to one Y3+ and one Tl1+ atom.
