Materials Data on Fe3Ni by Materials Project

Abstract

Fe3Ni 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 Ni atoms to form FeFe8Ni4 cuboctahedra that share corners with twelve equivalent FeFe8Ni4 cuboctahedra, edges with eight equivalent NiFe12 cuboctahedra, edges with sixteen equivalent FeFe8Ni4 cuboctahedra, faces with four equivalent NiFe12 cuboctahedra, and faces with fourteen equivalent FeFe8Ni4 cuboctahedra. All Fe–Fe bond lengths are 2.53 Å. All Fe–Ni bond lengths are 2.53 Å. Ni is bonded to twelve equivalent Fe atoms to form NiFe12 cuboctahedra that share corners with twelve equivalent NiFe12 cuboctahedra, edges with twenty-four equivalent FeFe8Ni4 cuboctahedra, faces with six equivalent NiFe12 cuboctahedra, and faces with twelve equivalent FeFe8Ni4 cuboctahedra.
