Materials Data on PrI2 by Materials Project
PrI2 is trigonal omega-like structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Pr is bonded to six I atoms to form edge-sharing PrI6 octahedra. There are three shorter (3.18 Å) and three longer (3.32 Å) Pr–I bond lengths. There are two inequivalent I sites. In the first I site, I is bonded in a distorted T-shaped geometry to three equivalent Pr atoms. In the second I site, I is bonded in a 3-coordinate geometry to three equivalent Pr atoms.
