Abstract

Mg16Al12Se 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 10-coordinate geometry to four Mg and six Al atoms. There are a spread of Mg–Mg bond distances ranging from 3.03–3.24 Å. There are a spread of Mg–Al bond distances ranging from 3.03–3.14 Å. In the second Mg site, Mg is bonded in a 1-coordinate geometry to three equivalent Mg, six equivalent Al, and one Se atom. All Mg–Al bond lengths are 3.10 Å. The Mg–Se bond length is 3.21 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 3.08–3.16 Å. There are a spread of Mg–Al bond distances ranging from 3.04–3.11 Å. In the fourth Mg site, Mg is bonded in a distorted single-bond geometry to six Mg, five Al, and one Se atom. There are two shorter (3.16 Å) and two longer (3.25 Å) Mg–Mg bond lengths. There are a spread of Mg–Al bond distances ranging from 2.97–3.25 Å. The Mg–Se bond length is 2.75 Å. In the fifth Mgmore »« less
