Title: Materials Data on Mg2Si3 by Materials Project

Abstract

Mg2Si3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a 8-coordinate geometry to eight Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.70–3.09 Å. In the second Mg2+ site, Mg2+ is bonded in a 9-coordinate geometry to nine Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.80–3.06 Å. In the third Mg2+ site, Mg2+ is bonded in a 8-coordinate geometry to eight Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.70–3.09 Å. In the fourth Mg2+ site, Mg2+ is bonded in a 9-coordinate geometry to nine Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.79–3.06 Å. There are six inequivalent Si+1.33- sites. In the first Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to five Mg2+ and four Si+1.33- atoms. There are a spread of Si–Si bond distances ranging from 2.38–2.62 Å. In the second Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to five Mg2+ and four Si+1.33- atoms. The Si–Si bond length is 2.39 Å. In the third Si+1.33- site, Si+1.33- ismore » bonded in a 9-coordinate geometry to seven Mg2+ and two Si+1.33- atoms. There are one shorter (2.39 Å) and one longer (2.43 Å) Si–Si bond lengths. In the fourth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to five Mg2+ and four Si+1.33- atoms. There are a spread of Si–Si bond distances ranging from 2.38–2.61 Å. In the fifth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to five Mg2+ and four Si+1.33- atoms. In the sixth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to seven Mg2+ and two Si+1.33- atoms.« less
