HgGe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Hg(1) is bonded to twelve equivalent Ge(1) atoms to form HgGe12 cuboctahedra that share corners with twelve equivalent Hg(1)Ge12 cuboctahedra, edges with twenty-four equivalent Ge(1)Hg4Ge8 cuboctahedra, faces with six equivalent Hg(1)Ge12 cuboctahedra, and faces with twelve equivalent Ge(1)Hg4Ge8 cuboctahedra. Ge(1) is bonded to four equivalent Hg(1) and eight equivalent Ge(1) atoms to form GeHg4Ge8 cuboctahedra that share corners with twelve equivalent Ge(1)Hg4Ge8 cuboctahedra, edges with eight equivalent Hg(1)Ge12 cuboctahedra, edges with sixteen equivalent Ge(1)Hg4Ge8 cuboctahedra, faces with four equivalent Hg(1)Ge12 cuboctahedra, and faces with fourteen equivalent Ge(1)Hg4Ge8 cuboctahedra.
