Materials Data on Be3Fe by Materials Project

Abstract

Be3Fe is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Be is bonded to eight equivalent Be and four equivalent Fe atoms to form BeBe8Fe4 cuboctahedra that share corners with twelve equivalent BeBe8Fe4 cuboctahedra, edges with eight equivalent FeBe12 cuboctahedra, edges with sixteen equivalent BeBe8Fe4 cuboctahedra, faces with four equivalent FeBe12 cuboctahedra, and faces with fourteen equivalent BeBe8Fe4 cuboctahedra. All Be–Be bond lengths are 2.29 Å. All Be–Fe bond lengths are 2.29 Å. Fe is bonded to twelve equivalent Be atoms to form FeBe12 cuboctahedra that share corners with twelve equivalent FeBe12 cuboctahedra, edges with twenty-four equivalent BeBe8Fe4 cuboctahedra, faces with six equivalent FeBe12 cuboctahedra, and faces with twelve equivalent BeBe8Fe4 cuboctahedra.
