Materials Data on Pr3I by Materials Project
Pr3I crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr is bonded in a distorted see-saw-like geometry to four equivalent I atoms. There are two shorter (3.57 Å) and two longer (3.58 Å) Pr–I bond lengths. I is bonded to twelve equivalent Pr atoms to form a mixture of corner and face-sharing IPr12 cuboctahedra.
