The structure described by RbSn 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 Sn(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to three equivalent Rb(2), four equivalent Rb(1), and three equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
