Materials Data on Li(Mg2Si)4 by Materials Project

Li(Mg2Si)4 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Li is bonded in a body-centered cubic geometry to eight equivalent Mg atoms. All Li–Mg bond lengths are 2.84 Å. Mg is bonded in a 5-coordinate geometry to one Li and four Si atoms. There are one shorter (2.72 Å) and three longer (2.80 Å) Mg–Si bond lengths. There are two inequivalent Si sites. In the first Si site, Si is bonded in a body-centered cubic geometry to eight equivalent Mg atoms. In the second Si site, Si is bonded in a body-centered cubic geometry to eight equivalent Mg atoms.
