Materials Data on RbS by Materials Project

Abstract

RbS is alpha boron-derived structured and crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six S1- atoms. There are four shorter (3.31 Å) and two longer (3.40 Å) Rb–S bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six S1- atoms. There are two shorter (3.40 Å) and four longer (3.52 Å) Rb–S bond lengths. There are two inequivalent S1- sites. In the first S1- site, S1- is bonded to six Rb1+ and one S1- atom to form a mixture of distorted face, edge, and corner-sharing SRb6S pentagonal bipyramids. The S–S bond length is 2.13 Å. In the second S1- site, S1- is bonded to six Rb1+ and one S1- atom to form a mixture of distorted face, edge, and corner-sharing SRb6S pentagonal bipyramids. The S–S bond length is 2.14 Å.
