Materials Data on Lu(Mg4Al3)4 by Materials Project
Abstract
Lu(Mg4Al3)4 is gamma-brass-derived 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 11-coordinate geometry to five Mg and six Al atoms. There are a spread of Mg–Mg bond distances ranging from 3.06–3.38 Å. There are a spread of Mg–Al bond distances ranging from 3.06–3.13 Å. In the second Mg site, Mg is bonded in a 3-coordinate geometry to seven Mg, one Lu, and five Al atoms. There are a spread of Mg–Mg bond distances ranging from 3.16–3.29 Å. The Mg–Lu bond length is 3.60 Å. There are a spread of Mg–Al bond distances ranging from 2.89–3.23 Å. In the third Mg site, Mg is bonded in a 9-coordinate geometry to three equivalent Mg, one Lu, and twelve Al atoms. The Mg–Lu bond length is 3.30 Å. There are a spread of Mg–Al bond distances ranging from 3.15–3.26 Å. In the fourth Mg site, Mg is bonded in a 1-coordinate geometry to seven Mg, one Lu, and five Al atoms. There are two shorter (3.13 Å) and two longer (3.15 Å) Mg–Mg bond lengths. The Mg–Lu bond length is 3.11 Å.more »
