The material structure described by Be3Fe is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Be(1) is bonded to eight equivalent Be(1) and four equivalent Fe(1) atoms to form BeBe8Fe4 cuboctahedra that share corners with twelve equivalent Be(1)Be8Fe4 cuboctahedra, edges with eight equivalent Fe(1)Be12 cuboctahedra, edges with sixteen equivalent Be(1)Be8Fe4 cuboctahedra, faces with four equivalent Fe(1)Be12 cuboctahedra, and faces with fourteen equivalent Be(1)Be8Fe4 cuboctahedra. Fe(1) is bonded to twelve equivalent Be(1) atoms to form FeBe12 cuboctahedra that share corners with twelve equivalent Fe(1)Be12 cuboctahedra, edges with twenty-four equivalent Be(1)Be8Fe4 cuboctahedra, faces with six equivalent Fe(1)Be12 cuboctahedra, and faces with twelve equivalent Be(1)Be8Fe4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
