Rb2Te5 crystallizes in the monoclinic C2/m space group. Rb(1) is bonded in a 9-coordinate geometry to one Te(1) and eight equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in an octahedral geometry to two equivalent Rb(1) and four equivalent Te(2) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one Te(1), and one Te(2) atom.
