Abstract
MgSi2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to two Mg and twelve Si atoms. There are one shorter (2.90 Å) and one longer (3.06 Å) Mg–Mg bond lengths. There are a spread of Mg–Si bond distances ranging from 2.77–3.05 Å. In the second Mg site, Mg is bonded in a 1-coordinate geometry to three Mg and ten Si atoms. There are one shorter (3.06 Å) and one longer (3.13 Å) Mg–Mg bond lengths. There are a spread of Mg–Si bond distances ranging from 2.79–3.18 Å. There are four inequivalent Si sites. In the first Si site, Si is bonded in a 10-coordinate geometry to six Mg and four Si atoms. There are a spread of Si–Si bond distances ranging from 2.46–2.64 Å. In the second Si site, Si is bonded in a 9-coordinate geometry to five Mg and four Si atoms. There are a spread of Si–Si bond distances ranging from 2.52–2.57 Å. In the third Si site, Si is bonded in a 9-coordinate geometry to five Mg and four Si atoms. There are one shorter (2.47more »
