The material structure described by Pr7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Rh(1) atoms. In the second Pr site, Pr(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. In the third Pr site, Pr(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to one Pr(1), two equivalent Pr(3), and three equivalent Pr(2) atoms. is represented by the CIF file [CIF]
