The crystal structure described by Tb2Te3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms to form a mixture of corner and edge-sharing TbTe6 octahedra. The corner-sharing octahedral tilt angles are 2°. In the second Tb site, Tb(2) is bonded to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms to form a mixture of corner and edge-sharing TbTe6 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 Tb(1) and two equivalent Tb(2) atoms. In the second Te site, Te(2) is bonded in a rectangular see-saw-like geometry to two equivalent Tb(1) and two equivalent Tb(2) atoms. In the third Te site, Te(3) is bonded in a rectangular see-saw-like geometry to two equivalent Tb(1) and two equivalent Tb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
