The crystal structure described by LiU2TmS3O2 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a distorted square co-planar geometry to one S(1), one S(2), and four equivalent O(1) atoms. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 8-coordinate geometry to four equivalent S(2) and four equivalent O(1) atoms. In the second U site, U(2) is bonded in a 8-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. Tm(1) is bonded to one S(1), one S(2), and four equivalent S(3) atoms to form a mixture of corner and edge-sharing TmS6 octahedra. The corner-sharing octahedral tilt angles are 5°. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to one Li(1), four equivalent U(2), and one Tm(1) atom. In the second S site, S(2) is bonded in a 6-coordinate geometry to one Li(1), four equivalent U(1), and one Tm(1) atom. In the third S site, S(3) is bonded in a rectangular see-saw-like geometry to four equivalent Tm(1) atoms. O(1) is bonded to two equivalent Li(1), two equivalent U(1), and two equivalent U(2) atoms to form a mixture of distorted corner, edge, and face-sharing OLi2U4 octahedra. The corner-sharing octahedral tilt angles are 1°. is represented by the Crystallographic Information File (CIF) [CIF]
