Lu2Te3 crystallizes in the orthorhombic Fddd space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of corner and edge-sharing LuTe6 octahedra. The corner-sharing octahedral tilt angles are 2°. In the second Lu site, Lu(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of corner and edge-sharing LuTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a rectangular see-saw-like geometry to two equivalent Lu(1) and two equivalent Lu(2) atoms. In the second Te site, Te(2) is bonded in a rectangular see-saw-like geometry to two equivalent Lu(1) and two equivalent Lu(2) atoms.

In the first Lu site, Lu(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of corner and edge-sharing LuTe6 octahedra. The corner-sharing octahedral tilt angles are 2°. Both Lu(1)-Te(1) bond lengths are 3.02 Å. There are two shorter (3.01 Å) and two longer (3.04 Å) Lu(1)-Te(2) bond lengths. In the second Lu site, Lu(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of corner and edge-sharing LuTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. Both Lu(2)-Te(1) bond lengths are 3.02 Å. All Lu(2)-Te(2) bond lengths are 3.01 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a rectangular see-saw-like geometry to two equivalent Lu(1) and two equivalent Lu(2) atoms. In the second Te site, Te(2) is bonded in a rectangular see-saw-like geometry to two equivalent Lu(1) and two equivalent Lu(2) atoms.
