Materials Data on Cs2ZrI6 by Materials Project
Cs2ZrI6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent I1- atoms to form CsI12 cuboctahedra that share corners with twelve equivalent CsI12 cuboctahedra, faces with six equivalent CsI12 cuboctahedra, and faces with four equivalent ZrI6 octahedra. All Cs–I bond lengths are 4.28 Å. Zr4+ is bonded to six equivalent I1- atoms to form ZrI6 octahedra that share faces with eight equivalent CsI12 cuboctahedra. All Zr–I bond lengths are 2.88 Å. I1- is bonded in a distorted single-bond geometry to four equivalent Cs1+ and one Zr4+ atom.
