Materials Data on ZnN6 by Materials Project

ZnN6 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of two ZnN6 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four N+0.33- atoms to form distorted corner-sharing ZnN4 tetrahedra. There are a spread of Zn–N bond distances ranging from 2.01–2.04 Å. In the second Zn2+ site, Zn2+ is bonded in a distorted see-saw-like geometry to four N+0.33- atoms. There are a spread of Zn–N bond distances ranging from 2.01–2.10 Å. There are eleven inequivalent N+0.33- sites. In the first N+0.33- site, N+0.33- is bonded in a linear geometry to two N+0.33- atoms. There is one shorter (1.15 Å) and one longer (1.22 Å) N–N bond length. In the second N+0.33- site, N+0.33- is bonded in a linear geometry to two equivalent N+0.33- atoms. Both N–N bond lengths are 1.18 Å. In the third N+0.33- site, N+0.33- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one N+0.33- atom. The N–N bond length is 1.23 Å. In the fourth N+0.33- site, N+0.33- is bonded in a single-bond geometry to one N+0.33- atom. The N–N bond length is 1.15 Å. In the fifth N+0.33- site, N+0.33- is bonded in a linear geometry to two N+0.33- atoms. In the sixth N+0.33- site, N+0.33- is bonded in a distorted bent 150 degrees geometry to one Zn2+ and one N+0.33- atom. In the seventh N+0.33- site, N+0.33- is bonded in a distorted linear geometry to one Zn2+ and one N+0.33- atom. The N–N bond length is 1.17 Å. In the eighth N+0.33- site, N+0.33- is bonded in a single-bond geometry to one N+0.33- atom. In the ninth N+0.33- site, N+0.33- is bonded in a linear geometry to two N+0.33- atoms. The N–N bond length is 1.18 Å. In the tenth N+0.33- site, N+0.33- is bonded in a distorted bent 120 degrees geometry to one Zn2+ and one N+0.33- atom. In the eleventh N+0.33- site, N+0.33- is bonded in a distorted trigonal planar geometry to two Zn2+ and one N+0.33- atom.
