Materials Data on Ba2LiAl(CN2)4 by Materials Project
LiBa2Al(CN2)4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Li1+ is bonded in a tetrahedral geometry to four N3- atoms. There are a spread of Li–N bond distances ranging from 2.07–2.14 Å. There are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight N3- atoms. There are a spread of Ba–N bond distances ranging from 2.92–2.99 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight N3- atoms. There are a spread of Ba–N bond distances ranging from 2.83–3.13 Å. Al3+ is bonded in a tetrahedral geometry to four N3- atoms. There is two shorter (1.85 Å) and two longer (1.86 Å) Al–N bond length. There are four inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.22 Å) and one longer (1.26 Å) C–N bond length. In the second C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.21 Å) and one longer (1.26 Å) C–N bond length. In the third C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.22 Å) and one longer (1.26 Å) C–N bond length. In the fourth C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.22 Å) and one longer (1.26 Å) C–N bond length. There are eight inequivalent N3- sites. In the first N3- site, N3- is bonded in a 2-coordinate geometry to two equivalent Ba2+, one Al3+, and one C4+ atom. In the second N3- site, N3- is bonded in a distorted bent 120 degrees geometry to two Ba2+, one Al3+, and one C4+ atom.
