The crystal structure described by Hg(AsO3)2 is beta Vanadium nitride-derived structured and crystallizes in the trigonal P-31m space group. Hg(1) is bonded to six equivalent O(1) atoms to form HgO6 octahedra that share corners with twelve equivalent As(1)O6 octahedra. The corner-sharing octahedral tilt angles are 53°. As(1) is bonded to six equivalent O(1) atoms to form AsO6 octahedra that share corners with six equivalent Hg(1)O6 octahedra and edges with three equivalent As(1)O6 octahedra. The corner-sharing octahedral tilt angles are 53°. O(1) is bonded in a distorted trigonal planar geometry to one Hg(1) and two equivalent As(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
