Materials Data on Rb4In2S5 by Materials Project

Abstract

Rb4In2S5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Rb–S bond distances ranging from 3.37–3.92 Å. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Rb–S bond distances ranging from 3.22–3.81 Å. In the third Rb1+ site, Rb1+ is bonded in a 3-coordinate geometry to six S2- atoms. There are a spread of Rb–S bond distances ranging from 3.31–3.86 Å. In the fourth Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Rb–S bond distances ranging from 3.37–3.93 Å. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to four S2- atoms to form a mixture of corner and edge-sharing InS4 tetrahedra. There are a spread of In–S bond distances ranging from 2.42–2.56 Å. In the second In3+ site, In3+ is bonded to four S2- atoms to form a mixture of corner and edge-sharing InS4 tetrahedra. There are a spread of In–S bond distances ranging from 2.43–2.53 Å. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a 7-coordinate geometry to six Rb1+ and one In3+ atom. In the second S2- site, S2- is bonded in a 5-coordinate geometry to four Rb1+ and two equivalent In3+ atoms. In the third S2- site, S2- is bonded in a 7-coordinate geometry to five Rb1+ and two In3+ atoms. In the fourth S2- site, S2- is bonded in a 6-coordinate geometry to four Rb1+ and two equivalent In3+ atoms. In the fifth S2- site, S2- is bonded in a 1-coordinate geometry to six Rb1+ and one In3+ atom.
