The structure described by HfNiSn 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 Ni(1) and four equivalent Sn(1) atoms. Ni(1) is bonded to four equivalent Hf(1) atoms to form NiHf4 tetrahedra that share corners with four equivalent Sn(1)Hf4 tetrahedra, corners with twelve equivalent Ni(1)Hf4 tetrahedra, and edges with six equivalent Sn(1)Hf4 tetrahedra. Sn(1) is bonded to four equivalent Hf(1) atoms to form SnHf4 tetrahedra that share corners with four equivalent Ni(1)Hf4 tetrahedra, corners with twelve equivalent Sn(1)Hf4 tetrahedra, and edges with six equivalent Ni(1)Hf4 tetrahedra. is represented by the CIF card [CIF]
