The structure described by Rb2SnTe5 crystallizes in the tetragonal I4cm space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to four equivalent Te(1) and four equivalent Te(2) atoms. In the second Rb site, Rb(2) is bonded in a distorted body-centered cubic geometry to four equivalent Te(1) and four equivalent Te(2) atoms. Sn(1) is bonded in a tetrahedral geometry to two equivalent Te(1) and two equivalent Te(2) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one Sn(1), and one Te(3) atom. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one Sn(1), and one Te(3) atom. In the third Te site, Te(3) is bonded in a square co-planar geometry to two equivalent Te(1) and two equivalent Te(2) atoms. is represented by the CIF card [CIF]
