Materials Data on Tb2In by Materials Project
Tb2In crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 6-coordinate geometry to eight Tb and six equivalent In atoms. There are two shorter (3.38 Å) and six longer (3.56 Å) Tb–Tb bond lengths. All Tb–In bond lengths are 3.56 Å. In the second Tb site, Tb is bonded to six equivalent Tb and five equivalent In atoms to form a mixture of face and corner-sharing TbTb6In5 trigonal bipyramids. There are three shorter (3.13 Å) and two longer (3.38 Å) Tb–In bond lengths. In is bonded in a 11-coordinate geometry to eleven Tb atoms.
