资源简介：
Mg3Y2(SiO4)3 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Mg2+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.36 Å) and four longer (2.44 Å) Mg–O bond lengths. Y3+ is bonded to six equivalent O2- atoms to form YO6 octahedra that share corners with six equivalent SiO4 tetrahedra. All Y–O bond lengths are 2.23 Å. Si4+ is bonded to four equivalent O2- atoms to form SiO4 tetrahedra that share corners with four equivalent YO6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Si–O bond lengths are 1.66 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+, one Y3+, and one Si4+ atom.
