PrI2 is trigonal omega-like structured and crystallizes in the cubic F-43m space group. Pr(1) is bonded to three equivalent I(1) and three equivalent I(2) atoms to form edge-sharing PrI6 octahedra. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted T-shaped geometry to three equivalent Pr(1) atoms. In the second I site, I(2) is bonded in a 3-coordinate geometry to three equivalent Pr(1) atoms.
