Abstract
Mg2Si3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight 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 2.72–3.00 Å. In the second 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 2.70–2.78 Å. In the third 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 2.72–2.96 Å. In the fourth Mg2+ site, Mg2+ is bonded to six Si+1.33- atoms to form distorted edge-sharing MgSi6 octahedra. There are a spread of Mg–Si bond distances ranging from 2.77–2.99 Å. In the fifth Mg2+ site, Mg2+ is bonded in a 4-coordinate geometry to seven Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.82–3.27 Å. In the sixth 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 2.73–3.00 Å. In the seventh Mg2+ site, Mg2+ is bonded in a 7-coordinate geometrymore »
