Sn3Ge is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sn(1) is bonded to eight equivalent Sn(1) and four equivalent Ge(1) atoms to form SnSn8Ge4 cuboctahedra that share corners with twelve equivalent Sn(1)Sn8Ge4 cuboctahedra, edges with eight equivalent Ge(1)Sn12 cuboctahedra, edges with sixteen equivalent Sn(1)Sn8Ge4 cuboctahedra, faces with four equivalent Ge(1)Sn12 cuboctahedra, and faces with fourteen equivalent Sn(1)Sn8Ge4 cuboctahedra. Ge(1) is bonded to twelve equivalent Sn(1) atoms to form GeSn12 cuboctahedra that share corners with twelve equivalent Ge(1)Sn12 cuboctahedra, edges with twenty-four equivalent Sn(1)Sn8Ge4 cuboctahedra, faces with six equivalent Ge(1)Sn12 cuboctahedra, and faces with twelve equivalent Sn(1)Sn8Ge4 cuboctahedra.
