Materials Data on Rb2TeI6 by Materials Project
Rb2TeI6 crystallizes in the tetragonal P4/mnc space group. The structure is three-dimensional. Rb1+ is bonded in a body-centered cubic geometry to eight I1- atoms. There are four shorter (3.89 Å) and four longer (4.13 Å) Rb–I bond lengths. Te4+ is bonded in an octahedral geometry to six I1- atoms. All Te–I bond lengths are 2.98 Å. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 3-coordinate geometry to two equivalent Rb1+ and one Te4+ atom. In the second I1- site, I1- is bonded to four equivalent Rb1+ and one Te4+ atom to form a mixture of distorted edge and corner-sharing IRb4Te square pyramids.
