The material described by HfMnTl is half-Heusler structured and crystallizes in the cubic F-43m space group. Hf(1) is bonded in a body-centered cubic geometry to four equivalent Mn(1) and four equivalent Tl(1) atoms. Mn(1) is bonded to four equivalent Hf(1) atoms to form distorted MnHf4 tetrahedra that share corners with four equivalent Tl(1)Hf4 tetrahedra, corners with twelve equivalent Mn(1)Hf4 tetrahedra, and edges with six equivalent Tl(1)Hf4 tetrahedra. Tl(1) is bonded to four equivalent Hf(1) atoms to form distorted TlHf4 tetrahedra that share corners with four equivalent Mn(1)Hf4 tetrahedra, corners with twelve equivalent Tl(1)Hf4 tetrahedra, and edges with six equivalent Mn(1)Hf4 tetrahedra. is represented by the CIF card [CIF]
