Materials Data on Cs2CN2 by Materials Project
Cs2CN2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of three Cs2CN2 ribbons oriented in the (-1, 1, 0) direction. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 2-coordinate geometry to two N3- atoms. There are one shorter (3.10 Å) and one longer (3.11 Å) Cs–N bond lengths. In the second Cs1+ site, Cs1+ is bonded in a 2-coordinate geometry to two N3- atoms. There are one shorter (3.09 Å) and one longer (3.13 Å) Cs–N bond lengths. C4+ is bonded in a linear geometry to two N3- atoms. Both C–N bond lengths are 1.25 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted single-bond geometry to two Cs1+ and one C4+ atom. In the second N3- site, N3- is bonded in a distorted single-bond geometry to two Cs1+ and one C4+ atom.
