Materials Data on S2N2O by Materials Project
N2S2O is alpha structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four N2S2O clusters. there are four inequivalent N3+ sites. In the first N3+ site, N3+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.58 Å) and one longer (1.63 Å) N–S bond length. In the second N3+ site, N3+ is bonded in a bent 150 degrees geometry to two S2- atoms. There is one shorter (1.57 Å) and one longer (1.59 Å) N–S bond length. In the third N3+ site, N3+ is bonded in a bent 150 degrees geometry to two S2- atoms. There is one shorter (1.57 Å) and one longer (1.59 Å) N–S bond length. In the fourth N3+ site, N3+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.57 Å) and one longer (1.63 Å) N–S bond length. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a tetrahedral geometry to two N3+ and two O2- atoms. There is one shorter (1.44 Å) and one longer (1.45 Å) S–O bond length. In the second S2- site, S2- is bonded in a bent 120 degrees geometry to two N3+ atoms. In the third S2- site, S2- is bonded in a distorted bent 120 degrees geometry to two N3+ atoms. In the fourth S2- site, S2- is bonded in a bent 120 degrees geometry to two N3+ atoms. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S2- atom.
