Materials Data on TbSnAu by Materials Project

TbAuSn crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Tb is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Sn atoms. There are three shorter (3.02 Å) and three longer (3.66 Å) Tb–Au bond lengths. There are three shorter (3.21 Å) and three longer (3.41 Å) Tb–Sn bond lengths. Au is bonded in a 10-coordinate geometry to six equivalent Tb and four equivalent Sn atoms. There are three shorter (2.83 Å) and one longer (2.99 Å) Au–Sn bond lengths. Sn is bonded in a 10-coordinate geometry to six equivalent Tb and four equivalent Au atoms.

Materials Data on Tb2SnAu2 by Materials Project

Tb2Au2Sn crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Tb is bonded in a 6-coordinate geometry to six equivalent Au and four equivalent Sn atoms. There are two shorter (2.96 Å) and four longer (3.07 Å) Tb–Au bond lengths. All Tb–Sn bond lengths are 3.50 Å. Au is bonded in a 9-coordinate geometry to six equivalent Tb, one Au, and two equivalent Sn atoms. The Au–Au bond length is 2.83 Å. Both Au–Sn bond lengths are 3.12 Å. Sn is bonded to eight equivalent Tb and four equivalent Au atoms to form a mixture of face and corner-sharing SnTb8Au4 cuboctahedra.
