UIrSn crystallizes in the hexagonal P-62m space group. U(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 U(1) and six equivalent Sn(1) atoms. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 12-coordinate geometry to six equivalent U(1), two equivalent Ir(1), two equivalent Ir(2), and two equivalent Sn(1) atoms.
UIrSn crystallizes in the hexagonal P-62m space group. U(1) is bonded in a 11-coordinate geometry to one Ir(2), four equivalent Ir(1), and six equivalent Sn(1) atoms. The U(1)-Ir(2) bond length is 3.13 Å. All U(1)-Ir(1) bond lengths are 3.00 Å. There are two shorter (3.16 Å) and four longer (3.40 Å) U(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 U(1) and six equivalent Sn(1) atoms. All Ir(2)-Sn(1) bond lengths are 2.75 Å. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Sn(1) atoms. All Ir(1)-Sn(1) bond lengths are 2.82 Å. Sn(1) is bonded in a 12-coordinate geometry to six equivalent U(1), two equivalent Ir(1), two equivalent Ir(2), and two equivalent Sn(1) atoms. Both Sn(1)-Sn(1) bond lengths are 3.19 Å.
