C3S3O2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four C3S3O2 ribbons oriented in the (1, 1, 0) direction. there are three inequivalent C+3.33+ sites. In the first C+3.33+ site, C+3.33+ is bonded in a distorted single-bond geometry to one S2- and one O2- atom. The C–S bond length is 1.78 Å. The C–O bond length is 1.21 Å. In the second C+3.33+ site, C+3.33+ is bonded in a trigonal planar geometry to three S2- atoms. There is one shorter (1.63 Å) and two longer (1.75 Å) C–S bond length. In the third C+3.33+ site, C+3.33+ is bonded in a distorted single-bond geometry to one S2- and one O2- atom. The C–S bond length is 1.78 Å. The C–O bond length is 1.21 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted water-like geometry to two C+3.33+ atoms. In the second S2- site, S2- is bonded in a 2-coordinate geometry to two C+3.33+ atoms. In the third S2- site, S2- is bonded in a distorted single-bond geometry to one C+3.33+ and one O2- atom. The S–O bond length is 3.47 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+3.33+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+3.33+ and one S2- atom.
