Tb6CoCl10 crystallizes in the triclinic P-1 space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to one Co(1), one Cl(1), one Cl(3), one Cl(5), and two equivalent Cl(2) atoms to form a mixture of corner and edge-sharing TbCoCl5 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second Tb site, Tb(2) is bonded to one Co(1), one Cl(2), one Cl(3), one Cl(5), and two equivalent Cl(4) atoms to form a mixture of corner and edge-sharing TbCoCl5 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. In the third Tb site, Tb(3) is bonded to one Co(1), one Cl(2), one Cl(3), one Cl(4), and two equivalent Cl(1) atoms to form a mixture of corner and edge-sharing TbCoCl5 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. Co(1) is bonded in an octahedral geometry to two equivalent Tb(1), two equivalent Tb(2), and two equivalent Tb(3) atoms. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a T-shaped geometry to one Tb(1) and two equivalent Tb(3) atoms. In the second Cl site, Cl(2) is bonded in a see-saw-like geometry to one Tb(2), one Tb(3), and two equivalent Tb(1) atoms. In the third Cl site, Cl(3) is bonded in a distorted trigonal non-coplanar geometry to one Tb(1), one Tb(2), and one Tb(3) atom. In the fourth Cl site, Cl(4) is bonded in a T-shaped geometry to one Tb(3) and two equivalent Tb(2) atoms. In the fifth Cl site, Cl(5) is bonded in an L-shaped geometry to one Tb(1) and one Tb(2) atom.
