Materials Data on Mg4Si3 by Materials Project
Abstract
Mg4Si3 is Magnesium tetraboride-like structured and 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 5-coordinate geometry to one Mg and six Si atoms. The Mg–Mg bond length is 2.99 Å. There are a spread of Mg–Si bond distances ranging from 2.76–3.17 Å. In the second Mg site, Mg is bonded in a 6-coordinate geometry to one Mg and seven Si atoms. The Mg–Mg bond length is 3.09 Å. There are a spread of Mg–Si bond distances ranging from 2.77–3.18 Å. In the third Mg site, Mg is bonded in a 4-coordinate geometry to four Si atoms. There are a spread of Mg–Si bond distances ranging from 2.65–2.99 Å. In the fourth Mg site, Mg is bonded in a 3-coordinate geometry to one Mg and three Si atoms. The Mg–Mg bond length is 3.26 Å. There are a spread of Mg–Si bond distances ranging from 2.79–2.99 Å. In the fifth Mg site, Mg is bonded in a 4-coordinate geometry to one Mg and five Si atoms. The Mg–Mg bond length is 3.09 Å. There are a spread of Mg–Si bond distances rangingmore »
