Materials Data on TmCuSn by Materials Project
TmCuSn is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tm is bonded to six equivalent Cu and six equivalent Sn atoms to form a mixture of edge and face-sharing TmCu6Sn6 cuboctahedra. All Tm–Cu bond lengths are 3.16 Å. All Tm–Sn bond lengths are 3.16 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Tm and three equivalent Sn atoms. All Cu–Sn bond lengths are 2.60 Å. Sn is bonded in a 9-coordinate geometry to six equivalent Tm and three equivalent Cu atoms.
