CaHgO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Ca(1) is bonded to twelve equivalent O(1) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Ca(1)O12 cuboctahedra, and faces with eight equivalent Hg(1)O6 octahedra. Hg(1) is bonded to six equivalent O(1) atoms to form HgO6 octahedra that share corners with six equivalent Hg(1)O6 octahedra and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Ca(1) and two equivalent Hg(1) atoms to form a mixture of distorted corner, edge, and face-sharing OCa4Hg2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
