Materials Data on Cs(SbS2)2 by Materials Project

Abstract

Cs(SbS2)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Cs1+ is bonded in a 9-coordinate geometry to nine S+1.75- atoms. There are a spread of Cs–S bond distances ranging from 3.52–3.88 Å. There are two inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded in a rectangular see-saw-like geometry to four S+1.75- atoms. There are a spread of Sb–S bond distances ranging from 2.46–2.96 Å. In the second Sb3+ site, Sb3+ is bonded in a distorted rectangular see-saw-like geometry to four S+1.75- atoms. There are a spread of Sb–S bond distances ranging from 2.44–2.85 Å. There are four inequivalent S+1.75- sites. In the first S+1.75- site, S+1.75- is bonded in a 4-coordinate geometry to two equivalent Cs1+ and two Sb3+ atoms. In the second S+1.75- site, S+1.75- is bonded in a 2-coordinate geometry to three equivalent Cs1+ and two Sb3+ atoms. In the third S+1.75- site, S+1.75- is bonded in a 1-coordinate geometry to three equivalent Cs1+, one Sb3+, and one S+1.75- atom. The S–S bond length is 2.09 Å. In the fourth S+1.75- site, S+1.75- is bonded to one Cs1+ and three Sb3+ atoms to form distorted edge-sharing SCsSb3 trigonal pyramids.
