Materials Data on Sb2S2O by Materials Project
Sb2S2O crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Sb2S2O sheet oriented in the (-1, 0, 1) direction. there are four inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded to five S2- atoms to form edge-sharing SbS5 square pyramids. There are a spread of Sb–S bond distances ranging from 2.46–3.08 Å. In the second Sb3+ site, Sb3+ is bonded to five S2- atoms to form distorted edge-sharing SbS5 square pyramids. There are a spread of Sb–S bond distances ranging from 2.47–3.19 Å. In the third Sb3+ site, Sb3+ is bonded in a 4-coordinate geometry to one S2- and three O2- atoms. The Sb–S bond length is 2.53 Å. There are a spread of Sb–O bond distances ranging from 2.05–2.18 Å. In the fourth Sb3+ site, Sb3+ is bonded in a distorted rectangular see-saw-like geometry to one S2- and three O2- atoms. The Sb–S bond length is 2.51 Å. There are a spread of Sb–O bond distances ranging from 2.05–2.20 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 2-coordinate geometry to three Sb3+ atoms. In the second S2- site, S2- is bonded in a 2-coordinate geometry to three Sb3+ atoms. In the third S2- site, S2- is bonded in a 3-coordinate geometry to three Sb3+ atoms. In the fourth S2- site, S2- is bonded in a 2-coordinate geometry to three Sb3+ atoms. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Sb3+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three Sb3+ atoms.
