ThNiSn is half-Heusler structured and crystallizes in the cubic F-43m space group. Th(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 Th(1) atoms to form NiTh4 tetrahedra that share corners with four equivalent Sn(1)Th4 tetrahedra, corners with twelve equivalent Ni(1)Th4 tetrahedra, and edges with six equivalent Sn(1)Th4 tetrahedra. Sn(1) is bonded to four equivalent Th(1) atoms to form SnTh4 tetrahedra that share corners with four equivalent Ni(1)Th4 tetrahedra, corners with twelve equivalent Sn(1)Th4 tetrahedra, and edges with six equivalent Ni(1)Th4 tetrahedra.
