Abstract

NH3OHNH4SO5 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four hydroxyammonium molecules and four NH4SO5 clusters. In each NH4SO5 cluster, N3+ is bonded in a distorted tetrahedral geometry to three H1+ and one O2- atom. All N–H bond lengths are 1.05 Å. The N–O bond length is 1.42 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3+ atom. In the fourth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.62 Å) H–O bond length. S2- is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.49–1.51 Å. There are five 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 distorted single-bond geometry to one S2- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one H1+ and one S2- atom. In the fifth O2- site, O2- is bonded in a water-like geometry to one N3+ and one H1+ atom.
