Tb6CoTe2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Te(1) atoms. In the second Tb site, Tb(2) is bonded in a 4-coordinate geometry to two equivalent Co(1) and two equivalent Te(1) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1) and six equivalent Tb(2) atoms. Te(1) is bonded in a 9-coordinate geometry to three equivalent Tb(2) and six equivalent Tb(1) atoms.
Tb6CoTe2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Te(1) atoms. The Tb(1)-Co(1) bond length is 3.36 Å. All Tb(1)-Te(1) bond lengths are 3.23 Å. In the second Tb site, Tb(2) is bonded in a 4-coordinate geometry to two equivalent Co(1) and two equivalent Te(1) atoms. Both Tb(2)-Co(1) bond lengths are 2.79 Å. Both Tb(2)-Te(1) bond lengths are 3.28 Å. Co(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1) and six equivalent Tb(2) atoms. Te(1) is bonded in a 9-coordinate geometry to three equivalent Tb(2) and six equivalent Tb(1) atoms.
