Materials Data on Mg2Sn by Materials Project

Abstract

Mg2Sn crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to nine Mg and three equivalent Sn atoms. There are a spread of Mg–Mg bond distances ranging from 3.09–3.33 Å. There are two shorter (3.12 Å) and one longer (3.22 Å) Mg–Sn bond lengths. In the second Mg site, Mg is bonded in a 12-coordinate geometry to four equivalent Mg and five equivalent Sn atoms. There are a spread of Mg–Sn bond distances ranging from 3.14–3.19 Å. Sn is bonded in a 12-coordinate geometry to eight Mg atoms.
