The compound described by Tb6OsI10 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 Os(1), one I(1), one I(2), one I(4), and two equivalent I(3) atoms to form a mixture of corner and edge-sharing TbOsI5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the second Tb site, Tb(2) is bonded to one Os(1), one I(1), one I(2), one I(3), and two equivalent I(5) atoms to form a mixture of distorted corner and edge-sharing TbOsI5 octahedra. The corner-sharing octahedral tilt angles range from 0-11°. In the third Tb site, Tb(3) is bonded to one Os(1), one I(2), one I(3), one I(5), and two equivalent I(4) atoms to form a mixture of distorted corner and edge-sharing TbOsI5 octahedra. The corner-sharing octahedral tilt angles range from 0-11°. Os(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 I sites. In the first I site, I(1) is bonded in a distorted L-shaped geometry to one Tb(1) and one Tb(2) atom. In the second I site, I(2) is bonded in a distorted T-shaped geometry to one Tb(1), one Tb(2), and one Tb(3) atom. In the third I site, I(3) is bonded in a rectangular see-saw-like geometry to one Tb(2), one Tb(3), and two equivalent Tb(1) atoms. In the fourth I site, I(4) is bonded in a distorted T-shaped geometry to one Tb(1) and two equivalent Tb(3) atoms. In the fifth I site, I(5) is bonded in a distorted T-shaped geometry to one Tb(3) and two equivalent Tb(2) atoms. is represented by the CIF file [CIF]
