Materials Data on Ba3(BN2)2 by Materials Project
Ba3(BN2)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 4-coordinate geometry to six N3- atoms. There are a spread of Ba–N bond distances ranging from 2.75–3.25 Å. In the second Ba2+ site, Ba2+ is bonded in a 5-coordinate geometry to five N3- atoms. There are a spread of Ba–N bond distances ranging from 2.74–3.09 Å. In the third Ba2+ site, Ba2+ is bonded to six N3- atoms to form edge-sharing BaN6 octahedra. There are a spread of Ba–N bond distances ranging from 2.85–3.05 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.34 Å) and one longer (1.36 Å) B–N bond length. In the second B3+ site, B3+ is bonded in a linear geometry to two N3- atoms. Both B–N bond lengths are 1.35 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted single-bond geometry to four Ba2+ and one B3+ atom. In the second N3- site, N3- is bonded in a distorted single-bond geometry to four Ba2+ and one B3+ atom. In the third N3- site, N3- is bonded in a distorted single-bond geometry to four Ba2+ and one B3+ atom. In the fourth N3- site, N3- is bonded in a distorted single-bond geometry to five Ba2+ and one B3+ atom.
