Gd2Fe3Al is Cubic Laves-derived structured and crystallizes in the trigonal R-3m space group. Gd(1) is bonded in a 16-coordinate geometry to four equivalent Gd(1), nine equivalent Fe(1), and three equivalent Al(1) atoms. Fe(1) is bonded to six equivalent Gd(1), four equivalent Fe(1), and two equivalent Al(1) atoms to form FeGd6Al2Fe4 cuboctahedra that share corners with four equivalent Al(1)Gd6Fe6 cuboctahedra, corners with fourteen equivalent Fe(1)Gd6Al2Fe4 cuboctahedra, edges with six equivalent Fe(1)Gd6Al2Fe4 cuboctahedra, faces with six equivalent Al(1)Gd6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)Gd6Al2Fe4 cuboctahedra. Al(1) is bonded to six equivalent Gd(1) and six equivalent Fe(1) atoms to form AlGd6Fe6 cuboctahedra that share corners with six equivalent Al(1)Gd6Fe6 cuboctahedra, corners with twelve equivalent Fe(1)Gd6Al2Fe4 cuboctahedra, edges with six equivalent Al(1)Gd6Fe6 cuboctahedra, and faces with eighteen equivalent Fe(1)Gd6Al2Fe4 cuboctahedra.
Gd2Fe3Al is Cubic Laves-derived structured and crystallizes in the trigonal R-3m space group. Gd(1) is bonded in a 16-coordinate geometry to four equivalent Gd(1), nine equivalent Fe(1), and three equivalent Al(1) atoms. There is one shorter (3.13 Å) and three longer (3.24 Å) Gd(1)-Gd(1) bond lengths. There are six shorter (3.06 Å) and three longer (3.09 Å) Gd(1)-Fe(1) bond lengths. All Gd(1)-Al(1) bond lengths are 3.09 Å. Fe(1) is bonded to six equivalent Gd(1), four equivalent Fe(1), and two equivalent Al(1) atoms to form FeGd6Al2Fe4 cuboctahedra that share corners with four equivalent Al(1)Gd6Fe6 cuboctahedra, corners with fourteen equivalent Fe(1)Gd6Al2Fe4 cuboctahedra, edges with six equivalent Fe(1)Gd6Al2Fe4 cuboctahedra, faces with six equivalent Al(1)Gd6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)Gd6Al2Fe4 cuboctahedra. All Fe(1)-Fe(1) bond lengths are 2.63 Å. Both Fe(1)-Al(1) bond lengths are 2.61 Å. Al(1) is bonded to six equivalent Gd(1) and six equivalent Fe(1) atoms to form AlGd6Fe6 cuboctahedra that share corners with six equivalent Al(1)Gd6Fe6 cuboctahedra, corners with twelve equivalent Fe(1)Gd6Al2Fe4 cuboctahedra, edges with six equivalent Al(1)Gd6Fe6 cuboctahedra, and faces with eighteen equivalent Fe(1)Gd6Al2Fe4 cuboctahedra.
