Materials Data on BaSi6N8O by Materials Project
BaSi6N8O crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Ba2+ is bonded in a 6-coordinate geometry to six N3- atoms. There are a spread of Ba–N bond distances ranging from 2.85–3.27 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four N3- atoms to form corner-sharing SiN4 tetrahedra. There are a spread of Si–N bond distances ranging from 1.69–1.79 Å. In the second Si4+ site, Si4+ is bonded to three N3- and one O2- atom to form corner-sharing SiN3O tetrahedra. There is one shorter (1.72 Å) and two longer (1.73 Å) Si–N bond length. The Si–O bond length is 1.63 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a 2-coordinate geometry to two equivalent Ba2+ and two equivalent Si4+ atoms. In the second N3- site, N3- is bonded in a trigonal planar geometry to three Si4+ atoms. In the third N3- site, N3- is bonded in a distorted trigonal planar geometry to one Ba2+ and three Si4+ atoms. O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms.
