The structure described by Tm8S11 crystallizes in the orthorhombic Cmcm space group. There are five inequivalent Tm sites. In the first Tm site, Tm(1) is bonded to one S(4), one S(6), two equivalent S(1), and two equivalent S(2) atoms to form TmS6 octahedra that share  a cornercorner with one Tm(5)S6 octahedra, corners with two equivalent Tm(2)S6 octahedra, corners with four equivalent Tm(3)S7 pentagonal bipyramids, edges with two equivalent Tm(1)S6 octahedra, edges with three equivalent Tm(2)S6 octahedra, and  an edgeedge with one Tm(3)S7 pentagonal bipyramid. The corner-sharing octahedral tilt angles range from 9-57°.

The corner-sharing octahedral tilt angles are 57°. There are six inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to one Tm(4), two equivalent Tm(1), and two equivalent Tm(2) atoms.
