The material described by Pr5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. In the second Pr site, Pr(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing PrIr4 tetrahedra. In the third Pr site, Pr(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Pr(3), three equivalent Pr(1), and three equivalent Pr(2) atoms. is represented by the CIF file [CIF]
