Title: Materials Data on MgSi2 by Materials Project

Abstract

MgSi2 is Zirconium Disilicide-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first 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 2.77–3.04 Å. In the second 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 2.77–3.04 Å. In the third 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 2.78–3.05 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 2.78–3.04 Å. There are eight inequivalent Si sites. In the first Si site, Si is bonded in a 8-coordinate geometry to four Mg and four Si atoms. There are a spread of Si–Si bond distances ranging from 2.49–2.64 Å. In the second Si site, Si is bonded in a 8-coordinate geometry to four Mg and four Si atoms. There are a spread of Si–Si bond distances rangingmore » from 2.48–2.63 Å. In the third Si site, Si is bonded in a 8-coordinate geometry to four Mg and four Si atoms. There are a spread of Si–Si bond distances ranging from 2.48–2.63 Å. In the fourth Si site, Si is bonded in a 10-coordinate geometry to four Mg and six Si atoms. There are a spread of Si–Si bond distances ranging from 2.62–2.71 Å. In the fifth Si site, Si is bonded in a 10-coordinate geometry to four Mg and six Si atoms. There are one shorter (2.68 Å) and one longer (2.70 Å) Si–Si bond lengths. In the sixth Si site, Si is bonded in a 10-coordinate geometry to four Mg and six Si atoms. Both Si–Si bond lengths are 2.49 Å. In the seventh Si site, Si is bonded in a 8-coordinate geometry to four Mg and four Si atoms. In the eighth Si site, Si is bonded in a 10-coordinate geometry to four Mg and six Si atoms.« less
