Materials Data on NbCoSn by Materials Project

Abstract

NbCoSn is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Nb is bonded in a body-centered cubic geometry to four equivalent Co and four equivalent Sn atoms. All Nb–Co bond lengths are 2.69 Å. All Nb–Sn bond lengths are 2.69 Å. Co is bonded to four equivalent Nb atoms to form distorted CoNb4 tetrahedra that share corners with four equivalent SnNb4 tetrahedra, corners with twelve equivalent CoNb4 tetrahedra, and edges with six equivalent SnNb4 tetrahedra. Sn is bonded to four equivalent Nb atoms to form distorted SnNb4 tetrahedra that share corners with four equivalent CoNb4 tetrahedra, corners with twelve equivalent SnNb4 tetrahedra, and edges with six equivalent CoNb4 tetrahedra.
