Materials Data on MgRhF6 by Materials Project
MgRhF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent F1- atoms to form MgF6 octahedra that share corners with six equivalent RhF6 octahedra. The corner-sharing octahedral tilt angles are 37°. All Mg–F bond lengths are 2.01 Å. Rh4+ is bonded to six equivalent F1- atoms to form RhF6 octahedra that share corners with six equivalent MgF6 octahedra. The corner-sharing octahedral tilt angles are 37°. All Rh–F bond lengths are 1.95 Å. F1- is bonded in a bent 150 degrees geometry to one Mg2+ and one Rh4+ atom.
