Materials Data on P2SN6 by Materials Project
(N2)2P2N2S crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight nitrogen molecules and four P2N2S clusters. In each P2N2S cluster, there are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a linear geometry to two N+1.33- atoms. There is one shorter (1.51 Å) and one longer (1.57 Å) P–N bond length. In the second P5+ site, P5+ is bonded in a bent 120 degrees geometry to one N+1.33- and one S2- atom. The P–N bond length is 1.68 Å. The P–S bond length is 1.92 Å. There are two inequivalent N+1.33- sites. In the first N+1.33- site, N+1.33- is bonded in a single-bond geometry to one P5+ atom. In the second N+1.33- site, N+1.33- is bonded in a bent 150 degrees geometry to two P5+ atoms. S2- is bonded in a distorted single-bond geometry to one P5+ atom.
