The crystal structure described by Pr2INi2 crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a 9-coordinate geometry to six equivalent Ni(1) and three equivalent I(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Ni(1) atoms. I(1) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. is represented by the CIF file [CIF]
