Title: Materials Data on Mg16Al13 by Materials Project

Abstract

Mg16Al13 is gamma-brass-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are five inequivalent Mg sites. In the first Mg site, Mg is bonded in a 1-coordinate geometry to three equivalent Mg and thirteen Al atoms. All Mg–Mg bond lengths are 3.17 Å. There are a spread of Mg–Al bond distances ranging from 3.03–3.23 Å. In the second Mg site, Mg is bonded in a 10-coordinate geometry to four Mg and six Al atoms. There are two shorter (3.02 Å) and one longer (3.03 Å) Mg–Mg bond lengths. There are a spread of Mg–Al bond distances ranging from 3.09–3.12 Å. In the third Mg site, Mg is bonded in a 12-coordinate geometry to seven Mg and five Al atoms. There are a spread of Mg–Mg bond distances ranging from 3.11–3.17 Å. There are a spread of Mg–Al bond distances ranging from 2.88–3.17 Å. In the fourth Mg site, Mg is bonded in a 6-coordinate geometry to six Mg and six Al atoms. Both Mg–Mg bond lengths are 3.15 Å. There are a spread of Mg–Al bond distances ranging from 2.91–3.11 Å. In the fifth Mg site, Mg is bonded in a 12-coordinate geometry tomore » seven Mg and five Al atoms. There are a spread of Mg–Al bond distances ranging from 2.86–3.18 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 11-coordinate geometry to seven Mg and four Al atoms. There are a spread of Al–Al bond distances ranging from 2.70–3.06 Å. In the second Al site, Al is bonded in a 11-coordinate geometry to eight Mg and three Al atoms. The Al–Al bond length is 2.69 Å. In the third Al site, Al is bonded in a 4-coordinate geometry to four Mg and six equivalent Al atoms. In the fourth Al site, Al is bonded in a 11-coordinate geometry to eight Mg and three Al atoms. Both Al–Al bond lengths are 2.76 Å.« less
