PrIrSn crystallizes in the hexagonal P-62m space group. Pr(1) is bonded in a 11-coordinate geometry to one Ir(2), four equivalent Ir(1), and six equivalent Sn(1) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(2) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Sn(1) atoms. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1), two equivalent Ir(1), and two equivalent Ir(2) atoms.
PrIrSn crystallizes in the hexagonal P-62m space group. Pr(1) is bonded in a 11-coordinate geometry to one Ir(2), four equivalent Ir(1), and six equivalent Sn(1) atoms. The Pr(1)-Ir(2) bond length is 3.09 Å. All Pr(1)-Ir(1) bond lengths are 3.08 Å. There are two shorter (3.29 Å) and four longer (3.42 Å) Pr(1)-Sn(1) bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir(2) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Sn(1) atoms. All Ir(2)-Sn(1) bond lengths are 2.81 Å. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Sn(1) atoms. All Ir(1)-Sn(1) bond lengths are 2.86 Å.
