Sc2Te3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. In the second Sc site, Sc(2) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. 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 Sc(1) and two equivalent Sc(2) atoms. In the second Te site, Te(2) is bonded in a square co-planar geometry to two equivalent Sc(1) and two equivalent Sc(2) atoms.

In the first Sc site, Sc(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. Both Sc(1)-Te(2) bond lengths are 2.90 Å. There are two shorter (2.90 Å) and two longer (2.96 Å) Sc(1)-Te(1) bond lengths. In the second Sc site, Sc(2) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. Both Sc(2)-Te(2) bond lengths are 2.94 Å. There are two shorter (2.91 Å) and two longer (2.94 Å) Sc(2)-Te(1) bond lengths.
