Materials Data on Pr2Co2I by Materials Project
Pr2Co2I crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr is bonded in a 9-coordinate geometry to six equivalent Co and three equivalent I atoms. There are three shorter (2.98 Å) and three longer (3.00 Å) Pr–Co bond lengths. All Pr–I bond lengths are 3.48 Å. Co is bonded in a 9-coordinate geometry to six equivalent Pr and three equivalent Co atoms. All Co–Co bond lengths are 2.33 Å. I is bonded in a 6-coordinate geometry to six equivalent Pr atoms.
