Materials Data on RbSb by Materials Project

Abstract

RbSb crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to five Sb1- atoms. There are a spread of Rb–Sb bond distances ranging from 3.70–3.88 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 3.73–4.00 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 (2.90 Å) and one longer (2.91 Å) Sb–Sb bond lengths. In the second Sb1- site, Sb1- is bonded in a 7-coordinate geometry to five Rb1+ and two equivalent Sb1- atoms.
