Tb2TeS2 is Corundum-derived structured and crystallizes in the orthorhombic Immm space group. Tb(1) is bonded to two equivalent Te(1) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing TbTe2S4 octahedra. The corner-sharing octahedral tilt angles range from 0-21°. Te(1) is bonded in a square co-planar geometry to four equivalent Tb(1) atoms. S(1) is bonded to four equivalent Tb(1) atoms to form a mixture of edge and corner-sharing STb4 trigonal pyramids.

Tb(1) is bonded to two equivalent Te(1) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing TbTe2S4 octahedra. The corner-sharing octahedral tilt angles range from 0-21°. Both Tb(1)-Te(1) bond lengths are 3.08 Å. There are two shorter (2.73 Å) and two longer (2.74 Å) Tb(1)-S(1) bond lengths. Te(1) is bonded in a square co-planar geometry to four equivalent Tb(1) atoms. S(1) is bonded to four equivalent Tb(1) atoms to form a mixture of edge and corner-sharing STb4 trigonal pyramids.
