Abstract

NS crystallizes in the triclinic P1 space group. The structure is one-dimensional and consists of four NS clusters and four NS ribbons oriented in the (1, 0, 0) direction. In two of the NS clusters, N1+ is bonded in a single-bond geometry to one S1- atom. The N–S bond length is 1.48 Å. S1- is bonded in a single-bond geometry to one N1+ atom. In two of the NS clusters, there are three inequivalent N1+ sites. In the first N1+ site, N1+ is bonded in a distorted single-bond geometry to one S1- atom. The N–S bond length is 1.61 Å. In the second N1+ site, N1+ is bonded in a bent 120 degrees geometry to two S1- atoms. There is one shorter (1.60 Å) and one longer (1.61 Å) N–S bond length. In the third N1+ site, N1+ is bonded in a bent 150 degrees geometry to two S1- atoms. There is one shorter (1.57 Å) and one longer (1.60 Å) N–S bond length. There are three inequivalent S1- sites. In the first S1- site, S1- is bonded in a water-like geometry to two N1+ atoms. In the second S1- site, S1- is bonded in a bent 120 degrees geometry to two N1+ atoms. In the third S1- site, S1- is bonded in a distorted single-bond geometry to one N1+ atom. In one of the NS ribbons, there are four inequivalent N1+ sites. In the first N1+ site, N1+ is bonded in a bent 120 degrees geometry to two S1- atoms. There is one shorter (1.58 Å) and one longer (1.69 Å) N–S bond length. In the second N1+ site, N1+ is bonded in a bent 120 degrees geometry to two S1- atoms. There is one shorter (1.59 Å) and one longer (1.69 Å) N–S bond length. In the third N1+ site, N1+ is bonded in a bent 120 degrees geometry to two S1- atoms. There is one shorter (1.59 Å) and one longer (1.72 Å) N–S bond length. In the fourth N1+ site, N1+ is bonded in a bent 120 degrees geometry to two S1- atoms. There is one shorter (1.59 Å) and one longer (1.72 Å) N–S bond length. There are four inequivalent S1- sites. In the first S1- site, S1- is bonded in a distorted trigonal non-coplanar geometry to three N1+ atoms. In the second S1- site, S1- is bonded in a distorted trigonal non-coplanar geometry to three N1+ atoms. In the third S1- site, S1- is bonded in a distorted single-bond geometry to one N1+ atom. In the fourth S1- site, S1- is bonded in a distorted single-bond geometry to one N1+ atom. In three of the NS ribbons, there are two inequivalent N1+ sites. In the first N1+ site, N1+ is bonded in a bent 150 degrees geometry to two S1- atoms. There is one shorter (1.59 Å) and one longer (1.62 Å) N–S bond length. In the second N1+ site, N1+ is bonded in a bent 150 degrees geometry to two S1- atoms. There is one shorter (1.59 Å) and one longer (1.62 Å) N–S bond length. There are two inequivalent S1- sites. In the first S1- site, S1- is bonded in a bent 120 degrees geometry to two N1+ atoms. In the second S1- site, S1- is bonded in a bent 120 degrees geometry to two N1+ atoms.
