Title: Materials Data on Mg4Si3 by Materials Project

Abstract

Mg4Si3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Mg sites. In the first Mg site, Mg is bonded in a 4-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.68–3.09 Å. In the second Mg site, Mg is bonded in a 4-coordinate geometry to four Si atoms. There are a spread of Mg–Si bond distances ranging from 2.71–2.90 Å. In the third Mg site, Mg is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.63–2.94 Å. In the fourth Mg site, Mg is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.71–3.09 Å. In the fifth Mg site, Mg is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.66–3.04 Å. In the sixth 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 2.73–3.03 Å. In the seventh Mg site, Mg is bonded in a 4-coordinate geometry to fivemore » Si atoms. There are a spread of Mg–Si bond distances ranging from 2.65–3.21 Å. In the eighth 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 2.68–3.13 Å. There are six inequivalent Si sites. In the first Si site, Si is bonded in a 7-coordinate geometry to six Mg and one Si atom. The Si–Si bond length is 2.37 Å. In the second Si site, Si is bonded in a 7-coordinate geometry to six Mg and one Si atom. In the third Si site, Si is bonded in a 8-coordinate geometry to seven Mg and one Si atom. The Si–Si bond length is 2.37 Å. In the fourth Si site, Si is bonded in a 8-coordinate geometry to seven Mg and one Si atom. The Si–Si bond length is 2.36 Å. In the fifth Si site, Si is bonded to seven Mg atoms to form distorted corner-sharing SiMg7 pentagonal bipyramids. In the sixth Si site, Si is bonded in a 8-coordinate geometry to six Mg and two Si atoms.« less
