The structure described by Pr2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 14-coordinate geometry to two equivalent Pr(1), six equivalent Pr(2), and six equivalent In(1) atoms. In the second Pr site, Pr(2) is bonded to six equivalent Pr(1) and five equivalent In(1) atoms to form a mixture of distorted corner and face-sharing PrPr6In5 trigonal bipyramids. In(1) is bonded in a 11-coordinate geometry to five equivalent Pr(2) and six equivalent Pr(1) atoms. is represented by the CIF file [CIF]
