资源简介：
Si2N3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Si4+ is bonded to four N+2.67- atoms to form corner-sharing SiN4 tetrahedra. There are a spread of Si–N bond distances ranging from 1.68–1.76 Å. There are two inequivalent N+2.67- sites. In the first N+2.67- site, N+2.67- is bonded in a trigonal planar geometry to three equivalent Si4+ atoms. In the second N+2.67- site, N+2.67- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms.
