Materials Data on SnHgF6 by Materials Project
HgSnF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Hg2+ is bonded to six equivalent F1- atoms to form HgF6 octahedra that share corners with six equivalent SnF6 octahedra. The corner-sharing octahedral tilt angles are 36°. All Hg–F bond lengths are 2.33 Å. Sn4+ is bonded to six equivalent F1- atoms to form SnF6 octahedra that share corners with six equivalent HgF6 octahedra. The corner-sharing octahedral tilt angles are 36°. All Sn–F bond lengths are 2.01 Å. F1- is bonded in a bent 150 degrees geometry to one Hg2+ and one Sn4+ atom.
