资源简介：
Mg2Si crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a distorted square co-planar geometry to four equivalent Si4- atoms. There are two shorter (2.96 Å) and two longer (3.00 Å) Mg–Si bond lengths. In the second Mg2+ site, Mg2+ is bonded to five equivalent Si4- atoms to form a mixture of edge and corner-sharing MgSi5 trigonal bipyramids. There are a spread of Mg–Si bond distances ranging from 2.65–3.07 Å. Si4- is bonded in a 3-coordinate geometry to nine Mg2+ atoms.
