Abstract

Mg2Si3 is Magnesium tetraboride-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a 8-coordinate geometry to eight Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.72–3.10 Å. In the second Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.63–2.89 Å. In the third Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.78–3.00 Å. In the fourth Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six Si+1.33- atoms. There are a spread of Mg–Si bond distances ranging from 2.75–3.12 Å.

There are a spread of Si–Si bond distances ranging from 2.37–2.55 Å. In the sixth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six Mg2+ and three Si+1.33- atoms. There are one shorter (2.49 Å) and two longer (2.53 Å) Si–Si bond lengths. In the seventh Si+1.33- site, Si+1.33- is bonded in a 6-coordinate geometry to six Mg2+ and two Si+1.33- atoms. The Si–Si bond length is 2.57 Å. In the eighth Si+1.33- site, Si+1.33- is bonded in a 7-coordinate geometry to four Mg2+ and three Si+1.33- atoms. There are one shorter (2.44 Å) and one longer (2.48 Å) Si–Si bond lengths. In the ninth Si+1.33- site, Si+1.33- is bonded in a 7-coordinate geometry to five Mg2+ and two equivalent Si+1.33- atoms. In the tenth Si+1.33- site, Si+1.33- is bonded in a 8-coordinate geometry to four Mg2+ and four Si+1.33- atoms. In the eleventh Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six Mg2+ and three Si+1.33- atoms. In the twelfth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six Mg2+ and three Si+1.33- atoms.« less
