Materials Data on RbSe by Materials Project

Abstract

RbSe 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 Se1- atoms. There are four shorter (3.47 Å) and two longer (3.54 Å) Rb–Se bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six Se1- atoms. There are two shorter (3.54 Å) and four longer (3.63 Å) Rb–Se bond lengths. There are two inequivalent Se1- sites. In the first Se1- site, Se1- is bonded in a 7-coordinate geometry to six Rb1+ and one Se1- atom. The Se–Se bond length is 2.43 Å. In the second Se1- site, Se1- is bonded in a 7-coordinate geometry to six Rb1+ and one Se1- atom. The Se–Se bond length is 2.44 Å.
