Materials Data on Ba3Si6N4O9 by Materials Project

Kristin Persson
Ba3Si6O9N4 crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.74 Å) and three longer (2.76 Å) Ba–O bond lengths. In the second Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to one N3- and six O2- atoms. The Ba–N bond length is 3.21 Å. There...
