Abstract

Mg3Si2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are seven inequivalent Mg sites. In the first Mg site, Mg is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.68–3.00 Å. In the second Mg site, Mg is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Mg–Si bond distances ranging from 2.76–2.94 Å. In the third Mg site, Mg is bonded in a distorted square co-planar geometry to four Si atoms. There are two shorter (2.83 Å) and two longer (2.92 Å) Mg–Si bond lengths. In the fourth Mg site, Mg is bonded in a distorted rectangular see-saw-like geometry to four Si atoms. There are a spread of Mg–Si bond distances ranging from 2.74–2.88 Å. In the fifth Mg site, Mg is bonded in a 5-coordinate geometry to six Si atoms. There are a spread of Mg–Si bond distances ranging from 2.71–3.14 Å. In the sixth 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 2.75–3.04 Å. In the seventh Mg site, Mg is bondedmore »« less
