The structure described by ZrNiSn is half-Heusler structured and crystallizes in the cubic F-43m space group. Zr(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 Zr(1) atoms to form NiZr4 tetrahedra that share corners with four equivalent Sn(1)Zr4 tetrahedra, corners with twelve equivalent Ni(1)Zr4 tetrahedra, and edges with six equivalent Sn(1)Zr4 tetrahedra. Sn(1) is bonded to four equivalent Zr(1) atoms to form SnZr4 tetrahedra that share corners with four equivalent Ni(1)Zr4 tetrahedra, corners with twelve equivalent Sn(1)Zr4 tetrahedra, and edges with six equivalent Ni(1)Zr4 tetrahedra. is represented by the CIF file [CIF]
