The compound described by Al2Te4O11 crystallizes in the monoclinic P2_1/c space group. Al(1) is bonded to one O(1), one O(3), one O(5), one O(6), and two equivalent O(2) atoms to form edge-sharing AlO6 octahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(3), one O(5), and one O(6) atom. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one O(2), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Al(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Al(1) and one Te(2) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Al(1) and one Te(1) atom. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent Te(2) atoms. In the fifth O site, O(5) is bonded in a distorted water-like geometry to one Al(1), one Te(1), and one Te(2) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Al(1) and one Te(1) atom. is represented by the CIF file [CIF]
