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.
