The crystal structure described by 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. is represented by the CIF file [CIF]
