Materials Data on Cs2RbLaCl6 by Materials Project

Abstract

Cs2RbLaCl6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent CsCl12 cuboctahedra, faces with six equivalent CsCl12 cuboctahedra, faces with four equivalent RbCl6 octahedra, and faces with four equivalent LaCl6 octahedra. All Cs–Cl bond lengths are 4.20 Å. Rb1+ is bonded to six equivalent Cl1- atoms to form RbCl6 octahedra that share corners with six equivalent LaCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–Cl bond lengths are 3.15 Å. La3+ is bonded to six equivalent Cl1- atoms to form LaCl6 octahedra that share corners with six equivalent RbCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All La–Cl bond lengths are 2.78 Å. Cl1- is bonded in a linear geometry to four equivalent Cs1+, one Rb1+, and one La3+ atom.
