UTl is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. U(1) is bonded to six equivalent U(1) and six equivalent Tl(1) atoms to form UU6Tl6 cuboctahedra that share corners with eighteen equivalent U(1)U6Tl6 cuboctahedra, edges with six equivalent U(1)U6Tl6 cuboctahedra, edges with twelve equivalent Tl(1)U6Tl6 cuboctahedra, faces with eight equivalent U(1)U6Tl6 cuboctahedra, and faces with twelve equivalent Tl(1)U6Tl6 cuboctahedra. Tl(1) is bonded to six equivalent U(1) and six equivalent Tl(1) atoms to form TlU6Tl6 cuboctahedra that share corners with eighteen equivalent Tl(1)U6Tl6 cuboctahedra, edges with six equivalent Tl(1)U6Tl6 cuboctahedra, edges with twelve equivalent U(1)U6Tl6 cuboctahedra, faces with eight equivalent Tl(1)U6Tl6 cuboctahedra, and faces with twelve equivalent U(1)U6Tl6 cuboctahedra.
