Materials Data on Tm2In by Materials Project
Tm2In crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 6-coordinate geometry to eight Tm and six equivalent In atoms. There are two shorter (3.35 Å) and six longer (3.49 Å) Tm–Tm bond lengths. All Tm–In bond lengths are 3.49 Å. In the second Tm site, Tm is bonded to six equivalent Tm and five equivalent In atoms to form a mixture of distorted corner and face-sharing TmTm6In5 trigonal bipyramids. There are three shorter (3.06 Å) and two longer (3.35 Å) Tm–In bond lengths. In is bonded in a 11-coordinate geometry to eleven Tm atoms.
