The crystal structure described by RbZn13 crystallizes in the cubic Fm-3c space group. Rb(1) is bonded in a 24-coordinate geometry to twenty-four equivalent Zn(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to twelve equivalent Zn(2) atoms to form a mixture of corner and face-sharing ZnZn12 cuboctahedra. In the second Zn site, Zn(2) is bonded to two equivalent Rb(1), one Zn(1), and nine equivalent Zn(2) atoms to form distorted ZnRb2Zn10 cuboctahedra that share  a cornercorner with one Zn(1)Zn12 cuboctahedra, corners with twenty-seven equivalent Zn(2)Rb2Zn10 cuboctahedra, edges with eight equivalent Zn(2)Rb2Zn10 cuboctahedra, faces with two equivalent Zn(1)Zn12 cuboctahedra, and faces with twenty-three equivalent Zn(2)Rb2Zn10 cuboctahedra. is represented by the CIF file [CIF]
