TbTe2 crystallizes in the tetragonal P4/nmm space group. Tb(1) is bonded in a 9-coordinate geometry to four equivalent Te(1) and five equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to four equivalent Tb(1) and four equivalent Te(1) atoms. In the second Te site, Te(2) is bonded to five equivalent Tb(1) atoms to form a mixture of distorted corner and edge-sharing TeTb5 trigonal bipyramids.
TbTe2 crystallizes in the tetragonal P4/nmm space group. Tb(1) is bonded in a 9-coordinate geometry to four equivalent Te(1) and five equivalent Te(2) atoms. All Tb(1)-Te(1) bond lengths are 3.28 Å. There is one shorter (3.19 Å) and four longer (3.27 Å) Tb(1)-Te(2) bond lengths. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to four equivalent Tb(1) and four equivalent Te(1) atoms. All Te(1)-Te(1) bond lengths are 3.14 Å. In the second Te site, Te(2) is bonded to five equivalent Tb(1) atoms to form a mixture of distorted corner and edge-sharing TeTb5 trigonal bipyramids.
