Materials Data on CuN3 by Materials Project
CuN3 crystallizes in the tetragonal I4_1/a space group. The structure is one-dimensional and consists of eight CuN3 ribbons oriented in the (0, 0, 1) direction. Cu1+ is bonded in a linear geometry to two equivalent N+0.33- atoms. Both Cu–N bond lengths are 1.84 Å. There are two inequivalent N+0.33- sites. In the first N+0.33- site, N+0.33- is bonded in a distorted bent 150 degrees geometry to one Cu1+ and one N+0.33- atom. The N–N bond length is 1.18 Å. In the second N+0.33- site, N+0.33- is bonded in a linear geometry to two equivalent N+0.33- atoms.
