The structure described by Y2TeO6 is Hydrophilite-derived structured and crystallizes in the trigonal P321 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted YO6 octahedra that share corners with four equivalent Te(1)O6 octahedra, corners with six equivalent Y(2)O6 octahedra, and  an edgeedge with one Te(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 45-58°. In the second Y site, Y(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted YO6 octahedra that share corners with two equivalent Te(2)O6 octahedra, corners with six equivalent Y(1)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-58°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form TeO6 octahedra that share corners with six equivalent Y(1)O6 octahedra and edges with three equivalent Y(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 45-52°. In the second Te site, Te(2) is bonded to six equivalent O(1) atoms to form TeO6 octahedra that share corners with six equivalent Y(2)O6 octahedra and edges with three equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Y(1), one Y(2), and one Te(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Y(1), one Y(2), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Y(1), one Y(2), and one Te(1) atom. is represented by the CIF card [CIF]
