Materials Data on Rb2InGaF6 by Materials Project

Abstract

Rb2InGaF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent F1- atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, faces with four equivalent InF6 octahedra, and faces with four equivalent GaF6 octahedra. All Rb–F bond lengths are 3.23 Å. In1+ is bonded to six equivalent F1- atoms to form InF6 octahedra that share corners with six equivalent GaF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All In–F bond lengths are 2.61 Å. Ga3+ is bonded to six equivalent F1- atoms to form GaF6 octahedra that share corners with six equivalent InF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ga–F bond lengths are 1.94 Å. F1- is bonded in a 1-coordinate geometry to four equivalent Rb1+, one In1+, and one Ga3+ atom.
