Materials Data on Mg6Si5 by Materials Project
Abstract
Mg6Si5 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are twelve inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a bent 150 degrees geometry to two Si+2.40- atoms. There are one shorter (2.85 Å) and one longer (2.93 Å) Mg–Si bond lengths. In the second Mg2+ site, Mg2+ is bonded in a rectangular see-saw-like geometry to four Si+2.40- atoms. There are a spread of Mg–Si bond distances ranging from 2.59–2.72 Å. In the third Mg2+ site, Mg2+ is bonded in a 7-coordinate geometry to seven Si+2.40- atoms. There are a spread of Mg–Si bond distances ranging from 2.73–2.99 Å. In the fourth Mg2+ site, Mg2+ is bonded in a 5-coordinate geometry to five Si+2.40- atoms. There are a spread of Mg–Si bond distances ranging from 2.75–3.01 Å. In the fifth Mg2+ site, Mg2+ is bonded in a see-saw-like geometry to four Si+2.40- atoms. There are a spread of Mg–Si bond distances ranging from 2.69–3.00 Å. In the sixth Mg2+ site, Mg2+ is bonded in a 5-coordinate geometry to five Si+2.40- atoms. There are a spread of Mg–Si bond distances ranging from 2.76–3.13 Å. In the seventh Mg2+ site, Mg2+ is bonded inmore »
