The crystal structure described by Tm2Te3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms to form a mixture of edge and corner-sharing TmTe6 octahedra. The corner-sharing octahedral tilt angles range from 1-2°. In the second Tm site, Tm(2) is bonded to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms to form a mixture of edge and corner-sharing TmTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a rectangular see-saw-like geometry to two equivalent Tm(1) and two equivalent Tm(2) atoms. In the second Te site, Te(2) is bonded in a rectangular see-saw-like geometry to two equivalent Tm(1) and two equivalent Tm(2) atoms. In the third Te site, Te(3) is bonded in a rectangular see-saw-like geometry to two equivalent Tm(1) and two equivalent Tm(2) atoms. is represented by the CIF card [CIF]
