Materials Data on RbSb by Materials Project
RbSb crystallizes in the monoclinic P2_1/c 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 Sb1- atoms. There are a spread of Rb–Sb bond distances ranging from 3.73–4.20 Å. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six Sb1- atoms. There are a spread of Rb–Sb bond distances ranging from 3.72–3.95 Å. There are two inequivalent Sb1- sites. In the first Sb1- site, Sb1- is bonded in a 8-coordinate geometry to six Rb1+ and two equivalent Sb1- atoms. There are one shorter (2.89 Å) and one longer (2.92 Å) Sb–Sb bond lengths. In the second Sb1- site, Sb1- is bonded in a 8-coordinate geometry to six Rb1+ and two equivalent Sb1- atoms.
