Materials Data on Rb2Te5 by Materials Project
Rb2Te5 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to nine Te+0.40- atoms. There are a spread of Rb–Te bond distances ranging from 3.75–4.02 Å. There are two inequivalent Te+0.40- sites. In the first Te+0.40- site, Te+0.40- is bonded in an octahedral geometry to two equivalent Rb1+ and four equivalent Te+0.40- atoms. All Te–Te bond lengths are 3.08 Å. In the second Te+0.40- site, Te+0.40- is bonded in a 7-coordinate geometry to four equivalent Rb1+ and three Te+0.40- atoms. There are one shorter (2.84 Å) and one longer (3.43 Å) Te–Te bond lengths.
