The material structure described by K(TeO3)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one O(2), one O(8), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(3), two equivalent O(5), two equivalent O(6), and two equivalent O(7) atoms. There are five inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(1) and four equivalent O(4) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 47°. In the second Te site, Te(2) is bonded to one O(8), two equivalent O(5), and two equivalent O(6) atoms to form corner-sharing TeO5 square pyramids. The corner-sharing octahedral tilt angles range from 38-63°. In the third Te site, Te(3) is bonded to two equivalent O(8) and four equivalent O(7) atoms to form TeO6 octahedra that share corners with four equivalent Te(5)O6 octahedra and corners with two equivalent Te(2)O5 square pyramids. The corner-sharing octahedral tilt angles are 45°. In the fourth Te site, Te(4) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(6) atoms to form TeO6 octahedra that share corners with two equivalent Te(1)O6 octahedra, corners with two equivalent Te(4)O6 octahedra, and corners with two equivalent Te(2)O5 square pyramids. The corner-sharing octahedral tilt angles range from 43-47°. In the fifth Te site, Te(5) is bonded to two equivalent O(3), two equivalent O(5), and two equivalent O(7) atoms to form TeO6 octahedra that share corners with two equivalent Te(3)O6 octahedra, corners with two equivalent Te(5)O6 octahedra, and corners with two equivalent Te(2)O5 square pyramids. The corner-sharing octahedral tilt angles range from 40-45°. There are eight inequivalent O sites. In the first O site, O(7) is bonded in a 2-coordinate geometry to one K(2), one Te(3), and one Te(5) atom. In the second O site, O(8) is bonded in a distorted bent 150 degrees geometry to one K(1), one Te(2), and one Te(3) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one K(2) and one Te(1) atom. In the fourth O site, O(2) is bonded in a 2-coordinate geometry to one K(1), one K(2), and two equivalent Te(4) atoms. In the fifth O site, O(3) is bonded in a 3-coordinate geometry to one K(2) and two equivalent Te(5) atoms. In the sixth O site, O(4) is bonded in a 3-coordinate geometry to one K(1), one Te(1), and one Te(4) atom. In the seventh O site, O(5) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Te(2), and one Te(5) atom. In the eighth O site, O(6) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Te(2), and one Te(4) atom. is represented by the Crystallographic Information File (CIF) [CIF]
