Abstract
Mg5Si6 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are ten inequivalent Mg sites. In the first Mg site, Mg is bonded in a 4-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.71–3.07 Å. In the second Mg site, Mg is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mg and five Si atoms. Both Mg–Mg bond lengths are 3.12 Å. There are a spread of Mg–Si bond distances ranging from 2.81–3.20 Å. In the third Mg site, Mg is bonded in a 5-coordinate geometry to one Mg and five Si atoms. The Mg–Mg bond length is 3.03 Å. There are a spread of Mg–Si bond distances ranging from 2.81–3.09 Å. In the fourth Mg site, Mg is bonded in a 9-coordinate geometry to nine Si atoms. There are a spread of Mg–Si bond distances ranging from 2.71–3.05 Å. In the fifth 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 2.73–2.96 Å. In the sixth Mg site, Mg is bonded in a 4-coordinate geometry to one Mg and four Si atoms.more »
