The crystal structure described by SbN9 is diamond structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of six SbN9 clusters. Sb(1) is bonded in a 3-coordinate geometry to three equivalent N(1) atoms. There are three inequivalent N sites. In the first N site, N(3) is bonded in a single-bond geometry to one N(2) atom. In the second N site, N(2) is bonded in a linear geometry to one N(1) and one N(3) atom. In the third N site, N(1) is bonded in a distorted bent 120 degrees geometry to one Sb(1) and one N(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
