AlFeBe4 crystallizes in the cubic F-43m space group. Be(1) is bonded to six equivalent Be(1), three equivalent Fe(1), and three equivalent Al(1) atoms to form a mixture of edge, face, and corner-sharing BeBe6Al3Fe3 cuboctahedra. Fe(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Al(1) atoms. Al(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Fe(1) atoms.

There are three shorter (2.08 Å) and three longer (2.14 Å) Be(1)-Be(1) bond lengths. All Be(1)-Fe(1) bond lengths are 2.47 Å. All Be(1)-Al(1) bond lengths are 2.48 Å. Fe(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Al(1) atoms. All Fe(1)-Al(1) bond lengths are 2.59 Å. Al(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Fe(1) atoms.
