Materials Data on Mg3Si4 by Materials Project
Abstract
Mg3Si4 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 2-coordinate geometry to two Mg and three Si atoms. There are one shorter (2.30 Å) and one longer (2.61 Å) Mg–Mg bond lengths. There are a spread of Mg–Si bond distances ranging from 2.63–2.84 Å. In the second Mg site, Mg is bonded in a distorted bent 150 degrees geometry to one Mg and two Si atoms. There are one shorter (2.12 Å) and one longer (2.48 Å) Mg–Si bond lengths. In the third Mg site, Mg is bonded in a 2-coordinate geometry to three Si atoms. There are a spread of Mg–Si bond distances ranging from 2.14–3.03 Å. In the fourth Mg site, Mg is bonded in a 2-coordinate geometry to three Si atoms. There are a spread of Mg–Si bond distances ranging from 1.81–2.61 Å. In the fifth Mg site, Mg is bonded in a 4-coordinate geometry to two Mg and two Si atoms. The Mg–Mg bond length is 1.87 Å. There are one shorter (2.80 Å) and one longer (3.00 Å) Mg–Si bond lengths. In the sixth Mg site,more »
