The crystal structure described by Tm2TeS2 crystallizes in the orthorhombic Immm space group. Tm(1) is bonded to two equivalent Te(1) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing TmTe2S4 octahedra. The corner-sharing octahedral tilt angles range from 0-20°. Te(1) is bonded in a square co-planar geometry to four equivalent Tm(1) atoms. S(1) is bonded in a see-saw-like geometry to four equivalent Tm(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
