The material described by Rb crystallizes in the cubic Pm-3n space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to twelve equivalent Rb(2) atoms to form a mixture of face and edge-sharing RbRb12 cuboctahedra. In the second Rb site, Rb(2) is bonded in a distorted linear geometry to two equivalent Rb(2) and four equivalent Rb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
