description: Ag2Sn(S2O7)3 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ag–O bond distances ranging from 2.52–2.93 Å. In the second Ag1+ site, Ag1+ is bonded in a 5-coordinate geometry to seven O2- atoms. There are a spread of Ag–O bond distances ranging from 2.46–3.22 Å. There are three inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SO4 tetrahedra. There are three shorter (2.08 Å) and three longer (2.09 Å) Sn–O bond lengths. In the second Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SO4 tetrahedra. There are three shorter (2.07 Å) and three longer (2.08 Å) Sn–O bond lengths. In the third Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SO4 tetrahedra. All Sn–O bond lengths are 2.08 Å. There are six inequivalent S6+ sites.
