Materials Data on Tm2SnAu2 by Materials Project
Tm2Au2Sn crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Tm is bonded in a 8-coordinate geometry to six Au and two equivalent Sn atoms. There are three shorter (3.01 Å) and three longer (3.02 Å) Tm–Au bond lengths. Both Tm–Sn bond lengths are 3.10 Å. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 6-coordinate geometry to six equivalent Tm atoms. In the second Au site, Au is bonded in a 6-coordinate geometry to six equivalent Tm atoms. Sn is bonded in a rectangular see-saw-like geometry to four equivalent Tm atoms.
