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 6-coordinate geometry to two Mg and four Si atoms. There are one shorter (1.95 Å) and one longer (2.87 Å) Mg–Mg bond lengths. There are a spread of Mg–Si bond distances ranging from 2.31–2.85 Å. In the second Mg site, Mg is bonded in a 1-coordinate geometry to one Mg and two Si atoms. The Mg–Mg bond length is 1.93 Å. There are one shorter (2.02 Å) and one longer (2.48 Å) Mg–Si bond lengths. In the third Mg site, Mg is bonded in a 4-coordinate geometry to one Mg and three Si atoms. The Mg–Mg bond length is 1.89 Å. There are a spread of Mg–Si bond distances ranging from 2.27–2.61 Å. In the fourth Mg site, Mg is bonded in a single-bond geometry to two Mg and one Si atom. The Mg–Mg bond length is 2.80 Å. The Mg–Si bond length is 1.75 Å. In the fifth Mg site, Mg is bonded in a 1-coordinate geometry to two Mg and three Si atoms. There are one shorter (1.93 Å) andmore »
