The material structure described by Rb is alpha structured and crystallizes in the cubic I-43m space group. The structure consists of two 7440-17-7 atoms inside a Rb framework. In the Rb framework, there are three inequivalent Rb sites. In the first Rb site, Rb(2) is bonded in a trigonal non-coplanar geometry to three equivalent Rb(3) atoms. In the second Rb site, Rb(3) is bonded in a 4-coordinate geometry to one Rb(2) and three equivalent Rb(4) atoms. In the third Rb site, Rb(4) is bonded in a 6-coordinate geometry to three equivalent Rb(3) and three equivalent Rb(4) atoms. is represented by the CIF card [CIF]
