Materials Data on S(IN)2 by Materials Project
S(NI)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one S(NI)2 sheet oriented in the (1, 1, -2) direction. there are four inequivalent N2+ sites. In the first N2+ site, N2+ is bonded in a 3-coordinate geometry to one S2- and two I1- atoms. The N–S bond length is 1.57 Å. There are one shorter (2.11 Å) and one longer (2.83 Å) N–I bond lengths. In the second N2+ site, N2+ is bonded in a 1-coordinate geometry to one S2- and two I1- atoms. The N–S bond length is 1.57 Å. There are one shorter (2.11 Å) and one longer (2.76 Å) N–I bond lengths. In the third N2+ site, N2+ is bonded in a 3-coordinate geometry to one S2- and two I1- atoms. The N–S bond length is 1.56 Å. There are one shorter (2.08 Å) and one longer (2.78 Å) N–I bond lengths. In the fourth N2+ site, N2+ is bonded in a distorted trigonal planar geometry to one S2- and two I1- atoms. The N–S bond length is 1.55 Å. There are one shorter (2.08 Å) and one longer (2.75 Å) N–I bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a bent 120 degrees geometry to two N2+ atoms. In the second S2- site, S2- is bonded in a bent 120 degrees geometry to two N2+ atoms. There are four inequivalent I1- sites. In the first I1- site, I1- is bonded in a linear geometry to two N2+ atoms. In the second I1- site, I1- is bonded in a distorted linear geometry to two N2+ atoms. In the third I1- site, I1- is bonded in a distorted linear geometry to two N2+ atoms. In the fourth I1- site, I1- is bonded in a distorted linear geometry to two N2+ atoms.
