Sr3Fe2Ag2S2O5 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to four equivalent S2- and four equivalent O2- atoms. All Sr–S bond lengths are 3.16 Å. All Sr–O bond lengths are 2.56 Å. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, and faces with eight equivalent FeO5 square pyramids. There are four shorter (2.84 Å) and eight longer (2.97 Å) Sr–O bond lengths. Fe3+ is bonded to five O2- atoms to form FeO5 square pyramids that share corners with five equivalent FeO5 square pyramids and faces with four equivalent SrO12 cuboctahedra. There is one shorter (1.92 Å) and four longer (2.03 Å) Fe–O bond length. Ag1+ is bonded in a 4-coordinate geometry to four equivalent S2- atoms. All Ag–S bond lengths are 2.70 Å. S2- is bonded in a 8-coordinate geometry to four equivalent Sr2+ and four equivalent Ag1+ atoms. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two equivalent Fe3+ atoms. In the second O2- site, O2- is bonded in a 6-coordinate geometry to four Sr2+ and two equivalent Fe3+ atoms.
