Abstract

Rb is Magnesium tetraboride-derived structured and 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 8-coordinate geometry to eight Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.66–5.11 Å. In the second Rb site, Rb is bonded in a 8-coordinate geometry to eight Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.59–5.03 Å. In the third Rb site, Rb is bonded in a 4-coordinate geometry to seven Rb atoms. There are a spread of Rb–Rb bond distances ranging from 4.68–5.08 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 4.69–5.12 Å. In the fifth 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 4.65–5.12 Å. In the sixth Rb site, Rb is bonded in a 8-coordinate geometry to eight Rb atoms. There are one shorter (4.68 Å) and one longer (4.90 Å) Rb–Rb bond lengths. In the seventh Rb site, Rb is bonded in a 4-coordinate geometry to eight Rb atoms. There are one shorter (5.03 Å) and one longer (5.17 Å) Rb–Rb bond lengths. In the eighth Rb site, Rb is bonded in a 8-coordinate geometry to eight Rb atoms.
