Materials Data on MgBi by Materials Project
MgBi crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are three inequivalent Mg sites. In the first Mg site, Mg is bonded in a 1-coordinate geometry to six Bi atoms. There are a spread of Mg–Bi bond distances ranging from 3.09–3.51 Å. In the second Mg site, Mg is bonded in a 7-coordinate geometry to seven Bi atoms. There are a spread of Mg–Bi bond distances ranging from 3.16–3.33 Å. In the third Mg site, Mg is bonded in a 7-coordinate geometry to seven Bi atoms. There are a spread of Mg–Bi bond distances ranging from 3.20–3.36 Å. There are three inequivalent Bi sites. In the first Bi site, Bi is bonded in a 7-coordinate geometry to seven Mg atoms. In the second Bi site, Bi is bonded in a 8-coordinate geometry to six Mg and two equivalent Bi atoms. Both Bi–Bi bond lengths are 3.38 Å. In the third Bi site, Bi is bonded in a 7-coordinate geometry to seven Mg atoms.
