Materials Data on Tb2Tl by Materials Project

Tb2Tl 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 Tl atoms. There are two shorter (3.38 Å) and six longer (3.57 Å) Tb–Tb bond lengths. All Tb–Tl bond lengths are 3.57 Å. In the second Tb site, Tb is bonded to six equivalent Tb and five equivalent Tl atoms to form a mixture of distorted face and corner-sharing TbTb6Tl5 trigonal bipyramids. There are three shorter (3.14 Å) and two longer (3.38 Å) Tb–Tl bond lengths. Tl is bonded in a 11-coordinate geometry to eleven Tb atoms.

Materials Data on TbTl3 by Materials Project

TbTl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tb is bonded to twelve equivalent Tl atoms to form TbTl12 cuboctahedra that share corners with twelve equivalent TbTl12 cuboctahedra, edges with twenty-four equivalent TlTb4Tl8 cuboctahedra, faces with six equivalent TbTl12 cuboctahedra, and faces with twelve equivalent TlTb4Tl8 cuboctahedra. All Tb–Tl bond lengths are 3.38 Å. Tl is bonded to four equivalent Tb and eight equivalent Tl atoms to form distorted TlTb4Tl8 cuboctahedra that share corners with twelve equivalent TlTb4Tl8 cuboctahedra, edges with eight equivalent TbTl12 cuboctahedra, edges with sixteen equivalent TlTb4Tl8 cuboctahedra, faces with four equivalent TbTl12 cuboctahedra, and faces with fourteen equivalent TlTb4Tl8 cuboctahedra. All Tl–Tl bond lengths are 3.38 Å.
