Materials Data on SnHgO3 by Materials Project

HgSnO3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Hg2+ is bonded in a distorted trigonal planar geometry to three equivalent O2- atoms. All Hg–O bond lengths are 2.25 Å. Sn4+ is bonded to six equivalent O2- atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles are 32°. All Sn–O bond lengths are 2.11 Å. O2- is bonded in a 3-coordinate geometry to one Hg2+ and two equivalent Sn4+ atoms.

Materials Data on SnHgO3 by Materials Project

HgSnO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Hg2+ is bonded to twelve equivalent O2- atoms to form HgO12 cuboctahedra that share corners with twelve equivalent HgO12 cuboctahedra, faces with six equivalent HgO12 cuboctahedra, and faces with eight equivalent SnO6 octahedra. All Hg–O bond lengths are 2.89 Å. Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent SnO6 octahedra and faces with eight equivalent HgO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sn–O bond lengths are 2.04 Å. O2- is bonded in a distorted linear geometry to four equivalent Hg2+ and two equivalent Sn4+ atoms.
