Materials Data on K2RbTbCl6 by Materials Project
(K)2RbTbCl6 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 RbTbCl6 framework. In the RbTbCl6 framework, Rb1+ is bonded to six equivalent Cl1- atoms to form RbCl6 octahedra that share corners with six equivalent TbCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–Cl bond lengths are 3.10 Å. Tb3+ is bonded to six equivalent Cl1- atoms to form TbCl6 octahedra that share corners with six equivalent RbCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Tb–Cl bond lengths are 2.64 Å. Cl1- is bonded in a linear geometry to one Rb1+ and one Tb3+ atom.
