Materials Data on SbN9 by Materials Project
SbN9 is diamond structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of six SbN9 clusters. Sb3+ is bonded in a 3-coordinate geometry to three equivalent N+0.33- atoms. All Sb–N bond lengths are 2.17 Å. There are three inequivalent N+0.33- sites. In the first 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 second 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 1.23 Å. In the third N+0.33- site, N+0.33- is bonded in a distorted bent 120 degrees geometry to one Sb3+ and one N+0.33- atom.
