Materials Data on K2LiRhF6 by Materials Project

Abstract

K2LiRhF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. K1+ is bonded to twelve equivalent F1- atoms to form KF12 cuboctahedra that share corners with twelve equivalent KF12 cuboctahedra, faces with six equivalent KF12 cuboctahedra, faces with four equivalent LiF6 octahedra, and faces with four equivalent RhF6 octahedra. All K–F bond lengths are 2.90 Å. Li1+ is bonded to six equivalent F1- atoms to form LiF6 octahedra that share corners with six equivalent RhF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Li–F bond lengths are 2.08 Å. Rh3+ is bonded to six equivalent F1- atoms to form RhF6 octahedra that share corners with six equivalent LiF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Rh–F bond lengths are 2.02 Å. F1- is bonded in a distorted linear geometry to four equivalent K1+, one Li1+, and one Rh3+ atom.
