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 3-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.69–3.14 Å. In the second Mg site, Mg is bonded to five Si atoms to form distorted corner-sharing MgSi5 tetrahedra. There are a spread of Mg–Si bond distances ranging from 2.67–3.12 Å. In the third 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 2.78–3.28 Å. In the fourth 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 2.73–2.91 Å. In the fifth 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 2.74–3.07 Å. In the sixth Mg site, Mg is bonded in a 5-coordinate geometry to six Si atoms. There are a spread of Mg–Si bond distances ranging from 2.74–3.19 Å. In the seventh Mg site, Mg is bonded in a 5-coordinate geometrymore » to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.75–2.95 Å. In the eighth Mg site, Mg is bonded in a 5-coordinate geometry to seven Si atoms. There are a spread of Mg–Si bond distances ranging from 2.76–3.24 Å. There are six inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to eight Mg and one Si atom. The Si–Si bond length is 2.59 Å. In the second Si site, Si is bonded in a 9-coordinate geometry to seven Mg and two Si atoms. There are one shorter (2.64 Å) and one longer (2.69 Å) Si–Si bond lengths. In the third Si site, Si is bonded in a 9-coordinate geometry to six Mg and three Si atoms. There are one shorter (2.58 Å) and one longer (2.59 Å) Si–Si bond lengths. In the fourth Si site, Si is bonded in a 8-coordinate geometry to seven Mg and one Si atom. In the fifth Si site, Si is bonded in a 5-coordinate geometry to seven Mg and three Si atoms. The Si–Si bond length is 2.78 Å. In the sixth Si site, Si is bonded in a 10-coordinate geometry to eight Mg and two Si atoms.« less
