Materials Data on NaLi2RhF6 by Materials Project

(Li)2NaRhF6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight lithium molecules and one NaRhF6 framework. In the NaRhF6 framework, Na1+ is bonded to six equivalent F1- atoms to form NaF6 octahedra that share corners with six equivalent RhF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Na–F bond lengths are 2.15 Å. Rh3+ is bonded to six equivalent F1- atoms to form RhF6 octahedra that share corners with six equivalent NaF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Rh–F bond lengths are 1.99 Å. F1- is bonded in a linear geometry to one Na1+ and one Rh3+ atom.

Materials Data on Na3Li3Rh2F12 by Materials Project

Na3Li3Rh2F12 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Na1+ is bonded in a distorted body-centered cubic geometry to eight equivalent F1- atoms. There are four shorter (2.42 Å) and four longer (2.58 Å) Na–F bond lengths. Li1+ is bonded to four equivalent F1- atoms to form LiF4 tetrahedra that share corners with four equivalent RhF6 octahedra. The corner-sharing octahedral tilt angles are 49°. All Li–F bond lengths are 1.88 Å. Rh3+ is bonded to six equivalent F1- atoms to form RhF6 octahedra that share corners with six equivalent LiF4 tetrahedra. All Rh–F bond lengths are 2.02 Å. F1- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Li1+, and one Rh3+ atom.
