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 4.71–5.05 Å. In the second 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 4.71–5.04 Å. In the third Rb site, Rb is bonded in a 9-coordinate geometry to nine Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.83–5.06 Å. In the fourth Rb site, Rb is bonded in a distorted hexagonal planar geometry to six Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.77–4.90 Å. In the fifth Rb site, Rb is bonded in a 7-coordinate geometry to eight Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.90–5.14 Å. In the sixth Rb site, Rb is bonded in a 8-coordinate geometry to nine Rb atoms. There are one shorter (4.89 Å) and one longer (5.00 Å) Rb–Rb bond lengths. In the seventh Rb site, Rb is bonded in a 7-coordinate geometry to seven Rb atoms. There are one shorter (4.74 Å) and one longer (5.09 Å) Rb–Rb bond lengths. In the eighth Rb site, Rb is bonded in a 9-coordinate geometry to nine Rb atoms.
