The structure described by KY(TeO3)2 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. Y(1) is bonded in an octahedral geometry to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted trigonal non-coplanar geometry to one O(2) and two equivalent O(1) atoms. In the second Te site, Te(2) is bonded in a distorted trigonal non-coplanar geometry to one O(4) and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a bent 120 degrees geometry to one Y(1) and one Te(2) atom. In the second O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Y(1), and one Te(1) atom. In the third O site, O(2) is bonded in a 2-coordinate geometry to two equivalent K(1), one Y(1), and one Te(1) atom. In the fourth O site, O(3) is bonded to two equivalent K(1), one Y(1), and one Te(2) atom to form a mixture of distorted corner and edge-sharing OK2YTe tetrahedra. is represented by the CIF file [CIF]
