Y(Mg4Al3)4 crystallizes in the cubic I-43m space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to seven Mg and five equivalent Al atoms. There are a spread of Mg–Mg bond distances ranging from 3.02–3.16 Å. There are a spread of Mg–Al bond distances ranging from 2.86–3.17 Å. In the second Mg site, Mg is bonded in a 10-coordinate geometry to three equivalent Mg, one Y, and six equivalent Al atoms. The Mg–Y bond length is 3.27 Å. All Mg–Al bond lengths are 3.16 Å. Y is bonded in a 12-coordinate geometry to four equivalent Mg and twelve equivalent Al atoms. All Y–Al bond lengths are 3.22 Å. Al is bonded in a 11-coordinate geometry to seven Mg, one Y, and three equivalent Al atoms. There are one shorter (2.70 Å) and two longer (2.78 Å) Al–Al bond lengths.
