Materials Data on SN2O3 by Materials Project

Abstract

N2(NSO3)2 is Silicon tetrafluoride-derived structured and crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of eight ammonia molecules and eight NSO3 clusters. In each NSO3 cluster, N4+ is bonded in a single-bond geometry to one S2- atom. The N–S bond length is 1.66 Å. S2- is bonded in a tetrahedral geometry to one N4+ and three O2- atoms. There is one shorter (1.46 Å) and two longer (1.47 Å) S–O bond length. There are three 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. In the third O2- site, O2- is bonded in a single-bond geometry to one S2- atom.
