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.

Materials Data on TbIn3 by Materials Project

TbIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tb is bonded to twelve equivalent In atoms to form TbIn12 cuboctahedra that share corners with twelve equivalent TbIn12 cuboctahedra, edges with twenty-four equivalent InTb4In8 cuboctahedra, faces with six equivalent TbIn12 cuboctahedra, and faces with twelve equivalent InTb4In8 cuboctahedra. All Tb–In bond lengths are 3.30 Å. In is bonded to four equivalent Tb and eight equivalent In atoms to form distorted InTb4In8 cuboctahedra that share corners with twelve equivalent InTb4In8 cuboctahedra, edges with eight equivalent TbIn12 cuboctahedra, edges with sixteen equivalent InTb4In8 cuboctahedra, faces with four equivalent TbIn12 cuboctahedra, and faces with fourteen equivalent InTb4In8 cuboctahedra. All In–In bond lengths are 3.30 Å.
