Materials Data on Mg5Si6 by Materials Project
Abstract
Mg5Si6 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Mg sites. In the first Mg site, Mg is bonded in a rectangular see-saw-like geometry to four Si atoms. There are a spread of Mg–Si bond distances ranging from 2.71–2.80 Å. In the second 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 2.86–3.21 Å. In the third 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 2.78–2.92 Å. In the fourth Mg site, Mg is bonded in a 7-coordinate geometry to seven Si atoms. There are a spread of Mg–Si bond distances ranging from 2.84–3.07 Å. In the fifth Mg site, Mg is bonded in a 2-coordinate geometry to nine Si atoms. There are a spread of Mg–Si bond distances ranging from 2.82–3.26 Å. There are six inequivalent Si sites. In the first Si site, Si is bonded in a 8-coordinate geometry to six Mg and two Si atoms. There are one shorter (2.40 Å) and one longer (2.41 Å) Si–Si bond lengths. In themore »
