Materials Data on CsI3 by Materials Project

CsI3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs is bonded in a 10-coordinate geometry to ten I atoms. There are a spread of Cs–I bond distances ranging from 3.95–4.55 Å. There are three inequivalent I sites. In the first I site, I is bonded in a distorted rectangular see-saw-like geometry to two equivalent Cs and two I atoms. There are one shorter (2.90 Å) and one longer (3.02 Å) I–I bond lengths. In the second I site, I is bonded in a 5-coordinate geometry to four equivalent Cs and one I atom. In the third I site, I is bonded in a 3-coordinate geometry to four equivalent Cs and one I atom.
