The crystal structure described by Eu4Al is Iron carbide-like structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of eight Eu4Al clusters. Eu(1) is bonded in a single-bond geometry to one Al(1) atom. Al(1) is bonded in a tetrahedral geometry to four equivalent Eu(1) atoms. is represented by the CIF file [CIF]
