Materials Data on Mg3Si4 by Materials Project
Abstract
Mg3Si4 is Magnesium tetraboride-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Mg sites. In the first Mg site, Mg is bonded in a 7-coordinate geometry to eight Si atoms. There are a spread of Mg–Si bond distances ranging from 2.77–3.15 Å. In the second Mg site, Mg is bonded to six Si atoms to form distorted corner-sharing MgSi6 trigonal bipyramids. There are a spread of Mg–Si bond distances ranging from 2.79–3.19 Å. In the third Mg site, Mg is bonded in a 6-coordinate geometry to six Si atoms. There are a spread of Mg–Si bond distances ranging from 2.73–2.94 Å. In the fourth Mg site, Mg is bonded in a 8-coordinate geometry to eight Si atoms. There are a spread of Mg–Si bond distances ranging from 2.69–3.09 Å. In the fifth Mg site, Mg is bonded in a 7-coordinate geometry to eight Si atoms. There are a spread of Mg–Si bond distances ranging from 2.80–3.17 Å. In the sixth Mg site, Mg is bonded in a 7-coordinate geometry to seven Si atoms. There are a spread of Mg–Si bond distances ranging from 2.88–3.05 Å. There are eight inequivalent Si sites.more »
