Materials Data on Fe3Sn by Materials Project

Abstract

Fe3Sn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Fe is bonded to eight equivalent Fe and four equivalent Sn atoms to form FeFe8Sn4 cuboctahedra that share corners with twelve equivalent FeFe8Sn4 cuboctahedra, edges with eight equivalent SnFe12 cuboctahedra, edges with sixteen equivalent FeFe8Sn4 cuboctahedra, faces with four equivalent SnFe12 cuboctahedra, and faces with fourteen equivalent FeFe8Sn4 cuboctahedra. All Fe–Fe bond lengths are 2.70 Å. All Fe–Sn bond lengths are 2.70 Å. Sn is bonded to twelve equivalent Fe atoms to form SnFe12 cuboctahedra that share corners with twelve equivalent SnFe12 cuboctahedra, edges with twenty-four equivalent FeFe8Sn4 cuboctahedra, faces with six equivalent SnFe12 cuboctahedra, and faces with twelve equivalent FeFe8Sn4 cuboctahedra.
