Pr5(Ir2Sn5)2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are three inequivalent Pr sites. In the first Pr site, Pr is bonded in a 8-coordinate geometry to four equivalent Ir and twelve Sn atoms. All Pr–Ir bond lengths are 3.51 Å. There are eight shorter (3.30 Å) and four longer (3.57 Å) Pr–Sn bond lengths. In the second Pr site, Pr is bonded to four equivalent Ir and eight Sn atoms to form distorted face-sharing PrSn8Ir4 cuboctahedra. All Pr–Ir bond lengths are 3.35 Å. There are a spread of Pr–Sn bond distances ranging from 3.18–3.37 Å. In the third Pr site, Pr is bonded in a 10-coordinate geometry to four equivalent Ir and ten Sn atoms. All Pr–Ir bond lengths are 3.67 Å. There are a spread of Pr–Sn bond distances ranging from 3.55–3.62 Å. Ir is bonded in a 10-coordinate geometry to five Pr and five Sn atoms. There are a spread of Ir–Sn bond distances ranging from 2.65–2.75 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 9-coordinate geometry to six Pr, two equivalent Ir, and one Sn atom. The Sn–Sn bond length is 2.79 Å. In the second Sn site, Sn is bonded in a 2-coordinate geometry to five Pr, two equivalent Ir, and three Sn atoms. There are one shorter (2.94 Å) and two longer (3.31 Å) Sn–Sn bond lengths. In the third Sn site, Sn is bonded in a 2-coordinate geometry to four Pr, two equivalent Ir, and two equivalent Sn atoms.
