Abstract

Rb crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Rb sites. In the first Rb site, Rb is bonded in a 7-coordinate geometry to seven Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.59–4.90 Å. In the second Rb site, Rb is bonded in a 6-coordinate geometry to six Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.47–5.04 Å. In the third Rb site, Rb is bonded in a 6-coordinate geometry to seven Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.73–5.11 Å. In the fourth Rb site, Rb is bonded in a 6-coordinate geometry to six Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.48–4.88 Å. In the fifth Rb site, Rb is bonded in a 6-coordinate geometry to six Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.79–5.10 Å. In the sixth Rb site, Rb is bonded in a 7-coordinate geometry to seven Rb atoms. The Rb–Rb bond length is 4.95 Å. In the seventh Rb site, Rb is bonded in a 7-coordinate geometry to seven Rb atoms. There are one shorter (4.87 Å) and one longer (4.93 Å) Rb–Rb bond lengths. In the eighth Rb site, Rb is bonded in a 6-coordinate geometry to six Rb atoms.
