Materials Data on TmSnIr by Materials Project
TmIrSn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Tm is bonded in a 11-coordinate geometry to five Ir and six equivalent Sn atoms. There are four shorter (2.99 Å) and one longer (3.03 Å) Tm–Ir bond lengths. There are two shorter (3.16 Å) and four longer (3.28 Å) Tm–Sn bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 9-coordinate geometry to three equivalent Tm and six equivalent Sn atoms. All Ir–Sn bond lengths are 2.76 Å. In the second Ir site, Ir is bonded in a 9-coordinate geometry to six equivalent Tm and three equivalent Sn atoms. All Ir–Sn bond lengths are 2.81 Å. Sn is bonded in a 10-coordinate geometry to six equivalent Tm and four Ir atoms.
