Materials Data on AgH20S6N5O9 by Materials Project
Ag(S2O3)3(NH4)5 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of twenty ammonium molecules and two Ag(S2O3)3 clusters. In each Ag(S2O3)3 cluster, Ag1+ is bonded to four S2- atoms to form edge-sharing AgS4 tetrahedra. There are a spread of Ag–S bond distances ranging from 2.56–2.78 Å. There are six 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 2.06 Å. There is two shorter (1.48 Å) and one longer (1.49 Å) S–O bond length. In the second S2- site, S2- is bonded in a trigonal non-coplanar geometry to one S2- and three O2- atoms. The S–S bond length is 2.03 Å. All S–O bond lengths are 1.49 Å. In the third 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. There is two shorter (1.49 Å) and one longer (1.50 Å) S–O bond length. In the fourth S2- site, S2- is bonded in a distorted water-like geometry to one Ag1+ and one S2- atom. In the fifth S2- site, S2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ag1+ and one S2- atom. In the sixth S2- site, S2- is bonded in a distorted water-like geometry to one Ag1+ and one S2- atom. There are nine 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. In the fourth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one S2- atom.
