Materials Data on RbI by Materials Project

RbI is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to six equivalent I1- atoms to form a mixture of corner and edge-sharing RbI6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–I bond lengths are 3.74 Å. I1- is bonded to six equivalent Rb1+ atoms to form a mixture of corner and edge-sharing IRb6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on RbI3 by Materials Project

RbI3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb is bonded in a 8-coordinate geometry to eight I atoms. There are a spread of Rb–I bond distances ranging from 3.80–4.13 Å. There are three inequivalent I sites. In the first I site, I is bonded in a distorted T-shaped geometry to two equivalent Rb and one I atom. The I–I bond length is 2.90 Å. In the second I site, I is bonded in a distorted rectangular see-saw-like geometry to two equivalent Rb and two I atoms. The I–I bond length is 3.02 Å. In the third I site, I is bonded in a 5-coordinate geometry to four equivalent Rb and one I atom.
