The structure described by Hg(BiO3)2 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Hg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form HgO6 octahedra that share corners with eight equivalent Bi(1)O6 octahedra and edges with two equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-55°. Bi(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form BiO6 octahedra that share corners with four equivalent Hg(1)O6 octahedra, corners with four equivalent Bi(1)O6 octahedra,  an edgeedge with one Hg(1)O6 octahedra, and  an edgeedge with one Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-55°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Hg(1) and two equivalent Bi(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to one Hg(1) and two equivalent Bi(1) atoms. is represented by the CIF card [CIF]
