The structure described by Yb2Te4O11 crystallizes in the monoclinic C2/c space group. Yb(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 to one O(1), one O(3), one O(5), and one O(6) atom to form corner-sharing TeO4 tetrahedra. In the second Te site, Te(2) is bonded in a distorted see-saw-like geometry to one O(2), one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a linear geometry to two equivalent Te(1) atoms. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Yb(1) and one Te(1) atom. In the third O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Yb(1) and one Te(2) atom. In the fourth O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Yb(1), one Te(1), and one Te(2) atom. In the fifth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Yb(1) and one Te(2) atom. In the sixth O site, O(5) is bonded in a 3-coordinate geometry to one Yb(1), one Te(1), and one Te(2) atom. is represented by the CIF card [CIF]
