The structure described by EuLaAl4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent La(1) and twelve equivalent Al(1) atoms. La(1) is bonded in a 16-coordinate geometry to four equivalent Eu(1) and twelve equivalent Al(1) atoms. Al(1) is bonded to three equivalent Eu(1), three equivalent La(1), and six equivalent Al(1) atoms to form a mixture of corner, edge, and face-sharing AlLa3Eu3Al6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
