The crystal structure described by RbGe crystallizes in the tetragonal I4_1/acd space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a distorted q6 geometry to three equivalent Rb(2), four equivalent Rb(1), and three equivalent Ge(1) atoms. is represented by the CIF card [CIF]
