Materials Data on Fe3Ge by Materials Project

Abstract

Fe3Ge 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 Ge atoms to form FeFe8Ge4 cuboctahedra that share corners with twelve equivalent FeFe8Ge4 cuboctahedra, edges with eight equivalent GeFe12 cuboctahedra, edges with sixteen equivalent FeFe8Ge4 cuboctahedra, faces with four equivalent GeFe12 cuboctahedra, and faces with fourteen equivalent FeFe8Ge4 cuboctahedra. All Fe–Fe bond lengths are 2.57 Å. All Fe–Ge bond lengths are 2.57 Å. Ge is bonded to twelve equivalent Fe atoms to form GeFe12 cuboctahedra that share corners with twelve equivalent GeFe12 cuboctahedra, edges with twenty-four equivalent FeFe8Ge4 cuboctahedra, faces with six equivalent GeFe12 cuboctahedra, and faces with twelve equivalent FeFe8Ge4 cuboctahedra.
