Materials Data on Mg17Al12 by Materials Project
Mg17Al12 crystallizes in the cubic I-43m space group. The structure is three-dimensional. there are three inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to four equivalent Mg and twelve equivalent Al atoms. All Mg–Mg bond lengths are 3.14 Å. All Mg–Al bond lengths are 3.20 Å. In the second Mg site, Mg is bonded in a 10-coordinate geometry to four Mg and six equivalent Al atoms. All Mg–Mg bond lengths are 3.06 Å. All Mg–Al bond lengths are 3.10 Å. In the third Mg site, Mg is bonded in a 12-coordinate geometry to seven Mg and five equivalent Al atoms. There are two shorter (3.14 Å) and four longer (3.16 Å) Mg–Mg bond lengths. There are a spread of Mg–Al bond distances ranging from 2.89–3.18 Å. Al is bonded in a 11-coordinate geometry to eight Mg and three equivalent Al atoms. There are one shorter (2.70 Å) and two longer (2.76 Å) Al–Al bond lengths.
