The compound described by Rb is alpha Samarium structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to six equivalent Rb(1) and six equivalent Rb(2) atoms to form a mixture of corner, edge, and face-sharing RbRb12 cuboctahedra. In the second Rb site, Rb(2) is bonded to three equivalent Rb(1) and nine equivalent Rb(2) atoms to form a mixture of distorted corner, edge, and face-sharing RbRb12 cuboctahedra. is represented by the CIF card [CIF]
