Materials Data on Hg(AsO3)2 by Materials Project

Hg(AsO3)2 crystallizes in the trigonal P-31m space group. The structure is three-dimensional. Hg2+ is bonded to six equivalent O2- atoms to form HgO6 octahedra that share corners with twelve equivalent AsO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All Hg–O bond lengths are 2.41 Å. As5+ is bonded to six equivalent O2- atoms to form AsO6 octahedra that share corners with six equivalent HgO6 octahedra and edges with three equivalent AsO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All As–O bond lengths are 1.87 Å. O2- is bonded in a distorted trigonal planar geometry to one Hg2+ and two equivalent As5+ atoms.
