资源简介：
Mg2Si is Cotunnite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded to four equivalent Si4- atoms to form a mixture of distorted corner and edge-sharing MgSi4 trigonal pyramids. There are a spread of Mg–Si bond distances ranging from 2.63–2.87 Å. In the second Mg2+ site, Mg2+ is bonded in a distorted see-saw-like geometry to four equivalent Si4- atoms. There are a spread of Mg–Si bond distances ranging from 2.70–2.90 Å. Si4- is bonded in a 8-coordinate geometry to eight Mg2+ atoms.
