Materials Data on RbSb3S5O by Materials Project
RbSb3S5O crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Rb1+ is bonded in a 1-coordinate geometry to five S2- and two equivalent O2- atoms. There are a spread of Rb–S bond distances ranging from 3.32–3.76 Å. There are one shorter (2.86 Å) and one longer (3.24 Å) Rb–O bond lengths. There are three inequivalent Sb+3.67+ sites. In the first Sb+3.67+ site, Sb+3.67+ is bonded in a see-saw-like geometry to four S2- atoms. There are a spread of Sb–S bond distances ranging from 2.45–2.77 Å. In the second Sb+3.67+ site, Sb+3.67+ is bonded in a distorted rectangular see-saw-like geometry to four S2- atoms. There are a spread of Sb–S bond distances ranging from 2.43–3.19 Å. In the third Sb+3.67+ site, Sb+3.67+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Sb–S bond distances ranging from 2.46–2.88 Å. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to one Rb1+ and three Sb+3.67+ atoms. In the second S2- site, S2- is bonded in a 2-coordinate geometry to one Rb1+ and two equivalent Sb+3.67+ atoms. In the third S2- site, S2- is bonded in a 2-coordinate geometry to three Sb+3.67+ atoms. In the fourth S2- site, S2- is bonded in a distorted single-bond geometry to one Rb1+, two Sb+3.67+, and one O2- atom. The S–O bond length is 1.54 Å. In the fifth S2- site, S2- is bonded to two equivalent Rb1+ and two Sb+3.67+ atoms to form distorted corner-sharing SRb2Sb2 trigonal pyramids. O2- is bonded in a 1-coordinate geometry to two equivalent Rb1+ and one S2- atom.
