Materials Data on CaRhF6 by Materials Project
CaRhF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent F1- atoms to form CaF6 octahedra that share corners with six equivalent RhF6 octahedra. The corner-sharing octahedral tilt angles are 39°. All Ca–F bond lengths are 2.29 Å. Rh4+ is bonded to six equivalent F1- atoms to form RhF6 octahedra that share corners with six equivalent CaF6 octahedra. The corner-sharing octahedral tilt angles are 39°. All Rh–F bond lengths are 1.95 Å. F1- is bonded in a bent 150 degrees geometry to one Ca2+ and one Rh4+ atom.
