Materials Data on S2NO by Materials Project
ONS2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four ONS2 clusters. In two of the ONS2 clusters, N2- is bonded in a bent 120 degrees geometry to two S2+ atoms. There is one shorter (1.55 Å) and one longer (1.67 Å) N–S bond length. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a single-bond geometry to one N2- atom. In the second S2+ site, S2+ is bonded in a bent 120 degrees geometry to one N2- and one O2- atom. The S–O bond length is 1.48 Å. O2- is bonded in a single-bond geometry to one S2+ atom.
