Abstract

Mg17GaAl11 is gamma-brass-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are eleven inequivalent Mg sites. In the first Mg site, Mg is bonded in a 10-coordinate geometry to four Mg and six Al atoms. There are a spread of Mg–Mg bond distances ranging from 3.05–3.14 Å. All Mg–Al bond lengths are 3.10 Å. In the second Mg site, Mg is bonded in a 12-coordinate geometry to four Mg, one Ga, and eleven Al atoms. There are one shorter (3.14 Å) and two longer (3.15 Å) Mg–Mg bond lengths. The Mg–Ga bond length is 3.23 Å. There are eight shorter (3.20 Å) and three longer (3.21 Å) Mg–Al bond lengths.

There are a spread of Mg–Al bond distances ranging from 2.90–3.18 Å. In the eleventh Mg site, Mg is bonded in a 12-coordinate geometry to seven Mg and five Al atoms. There are a spread of Mg–Al bond distances ranging from 2.90–3.17 Å. Ga is bonded in a 11-coordinate geometry to eight Mg and three Al atoms. There are one shorter (2.69 Å) and two longer (2.77 Å) Ga–Al bond lengths. There are six inequivalent Al sites. In the first Al site, Al is bonded in a 11-coordinate geometry to eight Mg, one Ga, and two equivalent Al atoms. Both Al–Al bond lengths are 2.77 Å. In the second Al site, Al is bonded in a 11-coordinate geometry to eight Mg and three Al atoms. There are one shorter (2.70 Å) and two longer (2.76 Å) Al–Al bond lengths.
