The structure described by Eu(Mg4Al3)4 crystallizes in the cubic I-43m space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to three equivalent Mg(2), one Eu(1), and six equivalent Al(1) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to one Mg(1), six equivalent Mg(2), and five equivalent Al(1) atoms. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1) and twelve equivalent Al(1) atoms. Al(1) is bonded in a 11-coordinate geometry to two equivalent Mg(1), five equivalent Mg(2), one Eu(1), and three equivalent Al(1) atoms. is represented by the CIF card [CIF]
