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 two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a 7-coordinate geometry to seven Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.76–2.89 Å. In the second Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.75–3.09 Å. There are three inequivalent Si+1.33- sites. In the first Si+1.33- site, Si+1.33- is bonded in a 6-coordinate geometry to three equivalent Mg2+ and three Si+1.33- atoms. There are one shorter (2.40 Å) and two longer (2.43 Å) Si–Si bond lengths. In the second Si+1.33- site, Si+1.33- is bonded in a 7-coordinate geometry to four Mg2+ and three Si+1.33- atoms. The Si–Si bond length is 2.43 Å. In the third Si+1.33- site, Si+1.33- is bonded in a 8-coordinate geometry to six Mg2+ and two Si+1.33- atoms. The Si–Si bond length is 2.46 Å.
