Fe3Al is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to eight equivalent Fe(1) and four equivalent Al(1) atoms to form FeAl4Fe8 cuboctahedra that share corners with twelve equivalent Fe(1)Al4Fe8 cuboctahedra, edges with eight equivalent Al(1)Fe12 cuboctahedra, edges with sixteen equivalent Fe(1)Al4Fe8 cuboctahedra, faces with four equivalent Al(1)Fe12 cuboctahedra, and faces with fourteen equivalent Fe(1)Al4Fe8 cuboctahedra. Al(1) is bonded to twelve equivalent Fe(1) atoms to form AlFe12 cuboctahedra that share corners with twelve equivalent Al(1)Fe12 cuboctahedra, edges with twenty-four equivalent Fe(1)Al4Fe8 cuboctahedra, faces with six equivalent Al(1)Fe12 cuboctahedra, and faces with twelve equivalent Fe(1)Al4Fe8 cuboctahedra.
