Materials Data on TmSnPd by Materials Project

TmPdSn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Tm is bonded in a 11-coordinate geometry to five Pd and six equivalent Sn atoms. There are four shorter (3.01 Å) and one longer (3.06 Å) Tm–Pd bond lengths. There are two shorter (3.20 Å) and four longer (3.30 Å) Tm–Sn bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 9-coordinate geometry to three equivalent Tm and six equivalent Sn atoms. All Pd–Sn bond lengths are 2.78 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to six equivalent Tm and three equivalent Sn atoms. All Pd–Sn bond lengths are 2.85 Å. Sn is bonded in a 10-coordinate geometry to six equivalent Tm and four Pd atoms.
