Ag6SbAsS6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three S2- atoms. There are a spread of Ag–S bond distances ranging from 2.46–2.86 Å. In the second Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three S2- atoms. There are a spread of Ag–S bond distances ranging from 2.44–2.95 Å. Sb3+ is bonded in a distorted T-shaped geometry to three equivalent S2- atoms. All Sb–S bond lengths are 2.50 Å. As3+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent S2- atoms. All As–S bond lengths are 2.32 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to three Ag1+ and one As3+ atom. In the second S2- site, S2- is bonded in a 4-coordinate geometry to three Ag1+ and one Sb3+ atom.
