Materials Data on Ce15B8N25 by Materials Project

Abstract

Ce15B8N25 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. there are three inequivalent Ce+3.40+ sites. In the first Ce+3.40+ site, Ce+3.40+ is bonded in a 9-coordinate geometry to nine N3- atoms. There are a spread of Ce–N bond distances ranging from 2.29–2.97 Å. In the second Ce+3.40+ site, Ce+3.40+ is bonded in a 8-coordinate geometry to eight N3- atoms. There are a spread of Ce–N bond distances ranging from 2.27–2.82 Å. In the third Ce+3.40+ site, Ce+3.40+ is bonded in a 8-coordinate geometry to eight N3- atoms. There are a spread of Ce–N bond distances ranging from 2.40–2.75 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three equivalent N3- atoms. All B–N bond lengths are 1.46 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three N3- atoms. There are a spread of B–N bond distances ranging from 1.46–1.49 Å. There are five inequivalent N3- sites. In the first N3- site, N3- is bonded in a 1-coordinate geometry to five Ce+3.40+ and one B3+ atom. In the second N3- site, N3- is bonded in an octahedral geometry to six equivalent Ce+3.40+ atoms. In the third N3- site, N3- is bonded in a distorted single-bond geometry to five Ce+3.40+ and one B3+ atom. In the fourth N3- site, N3- is bonded in a 1-coordinate geometry to five Ce+3.40+ and one B3+ atom. In the fifth N3- site, N3- is bonded in a distorted single-bond geometry to five Ce+3.40+ and one B3+ atom.
