The compound described by Pr3Rh2 crystallizes in the trigonal R-3 space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in an octahedral geometry to six equivalent Rh(1) atoms. In the second Pr site, Pr(2) is bonded in a 6-coordinate geometry to six equivalent Rh(1) atoms. In the third Pr site, Pr(3) is bonded in a 5-coordinate geometry to five equivalent Rh(1) atoms. Rh(1) is bonded in a 8-coordinate geometry to one Pr(1), two equivalent Pr(2), and five equivalent Pr(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
