Be4NiAl crystallizes in the cubic F-43m space group. Be(1) is bonded to six equivalent Be(1), three equivalent Ni(1), and three equivalent Al(1) atoms to form a mixture of face, corner, and edge-sharing BeBe6Al3Ni3 cuboctahedra. Ni(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 Ni(1) atoms.

There are three shorter (2.10 Å) and three longer (2.14 Å) Be(1)-Be(1) bond lengths. All Be(1)-Ni(1) bond lengths are 2.48 Å. All Be(1)-Al(1) bond lengths are 2.49 Å. Ni(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Al(1) atoms. All Ni(1)-Al(1) bond lengths are 2.60 Å. Al(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Ni(1) atoms.
