The structure described by HfTl crystallizes in the hexagonal P-6m2 space group. Hf(1) is bonded to six equivalent Hf(1) and six equivalent Tl(1) atoms to form HfHf6Tl6 cuboctahedra that share corners with eighteen equivalent Hf(1)Hf6Tl6 cuboctahedra, edges with six equivalent Hf(1)Hf6Tl6 cuboctahedra, edges with twelve equivalent Tl(1)Hf6Tl6 cuboctahedra, faces with eight equivalent Hf(1)Hf6Tl6 cuboctahedra, and faces with twelve equivalent Tl(1)Hf6Tl6 cuboctahedra.
