Abstract

Ag(S2O3)4(NH4)9(NO3)2 crystallizes in the tetragonal I-42d space group. The structure is zero-dimensional and consists of thirty-six ammonium molecules, eight nitric acid molecules, and four Ag(S2O3)4 clusters. In each Ag(S2O3)4 cluster, Ag1+ is bonded in a tetrahedral geometry to four equivalent S2- atoms. All Ag–S bond lengths are 2.59 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a trigonal non-coplanar geometry to one S2- and three O2- atoms. The S–S bond length is 2.04 Å. All S–O bond lengths are 1.49 Å. In the second S2- site, S2- is bonded in a distorted water-like geometry to one Ag1+ and one S2- atom. 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.
