Ce2Fe3Al is Cubic Laves-derived structured and crystallizes in the trigonal R-3m space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ce(1), nine equivalent Fe(1), and three equivalent Al(1) atoms. Fe(1) is bonded to six equivalent Ce(1), four equivalent Fe(1), and two equivalent Al(1) atoms to form FeCe6Al2Fe4 cuboctahedra that share corners with four equivalent Al(1)Ce6Fe6 cuboctahedra, corners with fourteen equivalent Fe(1)Ce6Al2Fe4 cuboctahedra, edges with six equivalent Fe(1)Ce6Al2Fe4 cuboctahedra, faces with six equivalent Al(1)Ce6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)Ce6Al2Fe4 cuboctahedra. Al(1) is bonded to six equivalent Ce(1) and six equivalent Fe(1) atoms to form AlCe6Fe6 cuboctahedra that share corners with six equivalent Al(1)Ce6Fe6 cuboctahedra, corners with twelve equivalent Fe(1)Ce6Al2Fe4 cuboctahedra, edges with six equivalent Al(1)Ce6Fe6 cuboctahedra, and faces with eighteen equivalent Fe(1)Ce6Al2Fe4 cuboctahedra.
Ce2Fe3Al is Cubic Laves-derived structured and crystallizes in the trigonal R-3m space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ce(1), nine equivalent Fe(1), and three equivalent Al(1) atoms. There is one shorter (3.02 Å) and three longer (3.31 Å) Ce(1)-Ce(1) bond lengths. There are six shorter (3.05 Å) and three longer (3.18 Å) Ce(1)-Fe(1) bond lengths. All Ce(1)-Al(1) bond lengths are 3.12 Å. Fe(1) is bonded to six equivalent Ce(1), four equivalent Fe(1), and two equivalent Al(1) atoms to form FeCe6Al2Fe4 cuboctahedra that share corners with four equivalent Al(1)Ce6Fe6 cuboctahedra, corners with fourteen equivalent Fe(1)Ce6Al2Fe4 cuboctahedra, edges with six equivalent Fe(1)Ce6Al2Fe4 cuboctahedra, faces with six equivalent Al(1)Ce6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)Ce6Al2Fe4 cuboctahedra. All Fe(1)-Fe(1) bond lengths are 2.64 Å. Both Fe(1)-Al(1) bond lengths are 2.64 Å. Al(1) is bonded to six equivalent Ce(1) and six equivalent Fe(1) atoms to form AlCe6Fe6 cuboctahedra that share corners with six equivalent Al(1)Ce6Fe6 cuboctahedra, corners with twelve equivalent Fe(1)Ce6Al2Fe4 cuboctahedra, edges with six equivalent Al(1)Ce6Fe6 cuboctahedra, and faces with eighteen equivalent Fe(1)Ce6Al2Fe4 cuboctahedra.
