HgGeO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Hg(1) is bonded to twelve equivalent O(1) atoms to form HgO12 cuboctahedra that share corners with twelve equivalent Hg(1)O12 cuboctahedra, faces with six equivalent Hg(1)O12 cuboctahedra, and faces with eight equivalent Ge(1)O6 octahedra. Ge(1) is bonded to six equivalent O(1) atoms to form GeO6 octahedra that share corners with six equivalent Ge(1)O6 octahedra and faces with eight equivalent Hg(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a linear geometry to four equivalent Hg(1) and two equivalent Ge(1) atoms.
