The compound described by Ho2Te4O11 crystallizes in the monoclinic C2/c space group. Ho(1) is bonded in a 8-coordinate geometry to one O(1), one O(5), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second Te site, Te(2) is bonded in a see-saw-like geometry to one O(1), one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Ho(1) and one Te(1) atom. In the second O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Ho(1), one Te(1), and one Te(2) atom. In the third O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Ho(1) and one Te(2) atom. In the fourth O site, O(6) is bonded in a bent 150 degrees geometry to two equivalent Te(2) atoms. In the fifth O site, O(1) is bonded in a 3-coordinate geometry to one Ho(1), one Te(1), and one Te(2) atom. In the sixth O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ho(1) and one Te(1) atom. is represented by the CIF file [CIF]
