Materials Data on CsK2InF6 by Materials Project
CsK2InF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to six equivalent F1- atoms to form CsF6 octahedra that share corners with six equivalent InF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Cs–F bond lengths are 2.78 Å. K1+ is bonded in a 12-coordinate geometry to twelve equivalent F1- atoms. All K–F bond lengths are 3.47 Å. In3+ is bonded to six equivalent F1- atoms to form InF6 octahedra that share corners with six equivalent CsF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All In–F bond lengths are 2.10 Å. F1- is bonded in a linear geometry to one Cs1+, four equivalent K1+, and one In3+ atom.
