Sc2Te3 crystallizes in the orthorhombic Fddd space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles are 1°. In the second Sc site, Sc(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. 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 rectangular see-saw-like 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(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles are 1°. Both Sc(1)-Te(1) bond lengths are 2.92 Å. There are two shorter (2.93 Å) and two longer (2.96 Å) Sc(1)-Te(2) bond lengths. In the second Sc site, Sc(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing ScTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. Both Sc(2)-Te(1) bond lengths are 2.94 Å. There are two shorter (2.91 Å) and two longer (2.94 Å) Sc(2)-Te(2) bond lengths. 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.
