Sc3Hg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sc(1) is bonded to eight equivalent Sc(1) and four equivalent Hg(1) atoms to form distorted ScSc8Hg4 cuboctahedra that share corners with twelve equivalent Sc(1)Sc8Hg4 cuboctahedra, edges with eight equivalent Hg(1)Sc12 cuboctahedra, edges with sixteen equivalent Sc(1)Sc8Hg4 cuboctahedra, faces with four equivalent Hg(1)Sc12 cuboctahedra, and faces with fourteen equivalent Sc(1)Sc8Hg4 cuboctahedra. Hg(1) is bonded to twelve equivalent Sc(1) atoms to form HgSc12 cuboctahedra that share corners with twelve equivalent Hg(1)Sc12 cuboctahedra, edges with twenty-four equivalent Sc(1)Sc8Hg4 cuboctahedra, faces with six equivalent Hg(1)Sc12 cuboctahedra, and faces with twelve equivalent Sc(1)Sc8Hg4 cuboctahedra.
