Ag3SbS3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.50–3.46 Å. In the second Ag1+ site, Ag1+ is bonded in a distorted bent 150 degrees geometry to two equivalent S2- atoms. There are one shorter (2.44 Å) and one longer (2.46 Å) Ag–S bond lengths. In the third Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.53–2.92 Å. Sb3+ is bonded in a 4-coordinate geometry to three S2- atoms. There are a spread of Sb–S bond distances ranging from 2.48–2.52 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to three Ag1+ and one Sb3+ atom. In the second S2- site, S2- is bonded in a 4-coordinate geometry to three Ag1+ and one Sb3+ atom. In the third S2- site, S2- is bonded in a 5-coordinate geometry to four Ag1+ and one Sb3+ atom.
