Materials Data on Li2Ca3N6 by Materials Project

Li2Ca3N6 crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six N+1.33- atoms to form distorted face-sharing LiN6 octahedra. There are a spread of Li–N bond distances ranging from 2.12–2.57 Å. In the second Li1+ site, Li1+ is bonded to six N+1.33- atoms to form distorted face-sharing LiN6 octahedra. There are a spread of Li–N bond distances ranging from 2.10–2.51 Å. There are four inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight N+1.33- atoms. There are a spread of Ca–N bond distances ranging from 2.46–2.58 Å. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight N+1.33- atoms. There are a spread of Ca–N bond distances ranging from 2.46–2.58 Å. In the third Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight N+1.33- atoms. There are a spread of Ca–N bond distances ranging from 2.37–2.65 Å. In the fourth Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight N+1.33- atoms. There are a spread of Ca–N bond distances ranging from 2.37–2.64 Å. There are six inequivalent N+1.33- sites. In the first N+1.33- site, N+1.33- is bonded in a 7-coordinate geometry to two equivalent Li1+, four Ca2+, and one N+1.33- atom. The N–N bond length is 1.31 Å. In the second N+1.33- site, N+1.33- is bonded in a 7-coordinate geometry to two equivalent Li1+, four Ca2+, and one N+1.33- atom. The N–N bond length is 1.32 Å. In the third N+1.33- site, N+1.33- is bonded in a 7-coordinate geometry to two equivalent Li1+, four Ca2+, and one N+1.33- atom. The N–N bond length is 1.32 Å. In the fourth N+1.33- site, N+1.33- is bonded in a 7-coordinate geometry to two equivalent Li1+, four Ca2+, and one N+1.33- atom. The N–N bond length is 1.30 Å. In the fifth N+1.33- site, N+1.33- is bonded in a 7-coordinate geometry to two equivalent Li1+, four Ca2+, and one N+1.33- atom. In the sixth N+1.33- site, N+1.33- is bonded in a 7-coordinate geometry to two equivalent Li1+, four Ca2+, and one N+1.33- atom.
