Materials Data on HgRhF6 by Materials Project
RhHgF6 is Upper Bainite-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Rh4+ is bonded to six equivalent F1- atoms to form RhF6 octahedra that share corners with six equivalent HgF6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Rh–F bond lengths are 1.95 Å. Hg2+ is bonded to six equivalent F1- atoms to form HgF6 octahedra that share corners with six equivalent RhF6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Hg–F bond lengths are 2.35 Å. F1- is bonded in a distorted bent 120 degrees geometry to one Rh4+ and one Hg2+ atom.
