The compound described by Rb crystallizes in the monoclinic C2/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a body-centered cubic geometry to four equivalent Rb(1) and four equivalent Rb(2) atoms. In the second Rb site, Rb(2) is bonded in a distorted body-centered cubic geometry to four equivalent Rb(1) and four equivalent Rb(2) atoms. is represented by the CIF card [CIF]
