Materials Data on Rb(SbSe2)2 by Materials Project
Rb(SbSe2)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to nine Se+1.75- atoms. There are a spread of Rb–Se bond distances ranging from 3.53–4.08 Å. There are two inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded to five Se+1.75- atoms to form distorted edge-sharing SbSe5 square pyramids. There are a spread of Sb–Se bond distances ranging from 2.59–3.35 Å. In the second Sb3+ site, Sb3+ is bonded in a see-saw-like geometry to four Se+1.75- atoms. There are a spread of Sb–Se bond distances ranging from 2.62–3.18 Å. There are four inequivalent Se+1.75- sites. In the first Se+1.75- site, Se+1.75- is bonded to one Rb1+ and three Sb3+ atoms to form distorted edge-sharing SeRbSb3 trigonal pyramids. In the second Se+1.75- site, Se+1.75- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two Sb3+ atoms. In the third Se+1.75- site, Se+1.75- is bonded in a 1-coordinate geometry to three equivalent Rb1+ and one Sb3+ atom. In the fourth Se+1.75- site, Se+1.75- is bonded in a 5-coordinate geometry to two equivalent Rb1+ and three Sb3+ atoms.
