PrIr2Ge2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr is bonded in a 8-coordinate geometry to eight Ir and eight Ge atoms. There are four shorter (3.27 Å) and four longer (3.36 Å) Pr–Ir bond lengths. There are four shorter (3.28 Å) and four longer (3.31 Å) Pr–Ge bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 9-coordinate geometry to four equivalent Pr and five Ge atoms. There are one shorter (2.46 Å) and four longer (2.51 Å) Ir–Ge bond lengths. In the second Ir site, Ir is bonded in a 4-coordinate geometry to four equivalent Pr and four equivalent Ge atoms. All Ir–Ge bond lengths are 2.53 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Pr and five Ir atoms. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Pr and four equivalent Ir atoms.
