Y2Te3 crystallizes in the orthorhombic Fddd space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing YTe6 octahedra. The corner-sharing octahedral tilt angles are 2°. In the second Y site, Y(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing YTe6 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 Y(1) and two equivalent Y(2) atoms. In the second Te site, Te(2) is bonded in a rectangular see-saw-like geometry to two equivalent Y(1) and two equivalent Y(2) atoms.

In the first Y site, Y(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing YTe6 octahedra. The corner-sharing octahedral tilt angles are 2°. Both Y(1)-Te(1) bond lengths are 3.08 Å. There are two shorter (3.08 Å) and two longer (3.09 Å) Y(1)-Te(2) bond lengths. In the second Y site, Y(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form a mixture of edge and corner-sharing YTe6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. Both Y(2)-Te(1) bond lengths are 3.09 Å. All Y(2)-Te(2) bond lengths are 3.08 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 Y(1) and two equivalent Y(2) atoms.
