The compound described by Y2TeO6 crystallizes in the monoclinic P2/c space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Y site, Y(2) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), one O(5), one O(6), and two equivalent O(1) atoms. In the third Y site, Y(3) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. Te(1) is bonded in a distorted octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Y(1), two equivalent Y(2), and one Te(1) atom to form a mixture of distorted edge and corner-sharing OY3Te tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Y(1), one Y(2), and one Te(1) atom. In the third O site, O(3) is bonded to one Y(1), one Y(2), one Y(3), and one Te(1) atom to form a mixture of distorted edge and corner-sharing OY3Te tetrahedra. In the fourth O site, O(4) is bonded to one Y(1), one Y(2), one Y(3), and one Te(1) atom to form a mixture of distorted edge and corner-sharing OY3Te tetrahedra. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Y(2), one Y(3), and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Y(2), one Y(3), and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
