Title: Materials Data on MgSi by Materials Project

Abstract

MgSi crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Mg sites. In the first Mg site, Mg is bonded in a 2-coordinate geometry to four Si atoms. There are a spread of Mg–Si bond distances ranging from 2.47–2.89 Å. In the second Mg site, Mg is bonded in a 1-coordinate geometry to three Si atoms. There are a spread of Mg–Si bond distances ranging from 2.39–3.17 Å. In the third Mg site, Mg is bonded in a 3-coordinate geometry to three equivalent Si atoms. There are a spread of Mg–Si bond distances ranging from 2.78–2.88 Å. There are three inequivalent Si sites. In the first Si site, Si is bonded in a 2-coordinate geometry to two Mg and two equivalent Si atoms. There are one shorter (2.26 Å) and one longer (2.55 Å) Si–Si bond lengths. In the second Si site, Si is bonded in a 6-coordinate geometry to five Mg and one Si atom. The Si–Si bond length is 2.27 Å. In the third Si site, Si is bonded in a 6-coordinate geometry to three equivalent Mg and three Si atoms. The Si–Si bond length is 2.17 Å.
