Materials Data on Mg4Si3 by Materials Project
Abstract
Mg4Si3 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one Mg4Si3 ribbon oriented in the (1, 0, 0) direction. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 1-coordinate geometry to one Si atom. The Mg–Si bond length is 2.14 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 1.94 Å. There are one shorter (2.16 Å) and one longer (2.73 Å) Mg–Si bond lengths. In the third Mg site, Mg is bonded in a 1-coordinate geometry to two equivalent Mg and two equivalent Si atoms. There are one shorter (2.06 Å) and one longer (2.63 Å) Mg–Mg bond lengths. There are one shorter (2.25 Å) and one longer (2.57 Å) Mg–Si bond lengths. In the fourth Mg site, Mg is bonded in a 6-coordinate geometry to three Mg and three Si atoms. There are a spread of Mg–Si bond distances ranging from 2.78–3.00 Å. There are three inequivalent Si sites. In the first Si site, Si is bonded in a 1-coordinate geometry to one Mg atom. In the second Simore »
