Materials Data on Mg2Bi by Materials Project

Abstract

BiMg2 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to three Bi atoms. There are one shorter (3.14 Å) and two longer (3.24 Å) Mg–Bi bond lengths. In the second Mg site, Mg is bonded in a 5-coordinate geometry to five Bi atoms. There are a spread of Mg–Bi bond distances ranging from 3.20–3.42 Å. In the third Mg site, Mg is bonded in a 12-coordinate geometry to four Bi atoms. There are a spread of Mg–Bi bond distances ranging from 3.15–3.37 Å. In the fourth Mg site, Mg is bonded in a 12-coordinate geometry to four Bi atoms. All Mg–Bi bond lengths are 3.22 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 10-coordinate geometry to eight Mg atoms. In the second Bi site, Bi is bonded in a 10-coordinate geometry to eight Mg atoms.
