The crystal structure described by Al2Te3 crystallizes in the monoclinic Cc space group. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to one Te(2), one Te(3), and two equivalent Te(1) atoms to form corner-sharing AlTe4 tetrahedra. In the second Al site, Al(2) is bonded to one Te(1), one Te(3), and two equivalent Te(2) atoms to form corner-sharing AlTe4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a trigonal non-coplanar geometry to one Al(2) and two equivalent Al(1) atoms. In the second Te site, Te(2) is bonded in a trigonal non-coplanar geometry to one Al(1) and two equivalent Al(2) atoms. In the third Te site, Te(3) is bonded in a water-like geometry to one Al(1) and one Al(2) atom. is represented by the CIF file [CIF]
