The material described by KTeO4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(6), one O(8), and two equivalent O(4) atoms. In the second K site, K(2) is bonded in a 5-coordinate geometry to one O(3), one O(6), one O(7), and two equivalent O(1) 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(7), and two equivalent O(2) atoms to form distorted edge-sharing TeO5 trigonal bipyramids. In the second Te site, Te(2) is bonded in a distorted rectangular see-saw-like geometry to one O(6), one O(7), and two equivalent O(4) atoms. There are eight inequivalent O sites. In the first O site, O(5) is bonded in a single-bond geometry to one O(8) atom. In the second O site, O(6) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one Te(2) atom. In the third O site, O(7) is bonded in a 3-coordinate geometry to one K(2), one Te(1), and one Te(2) atom. In the fourth O site, O(8) is bonded in a water-like geometry to one K(1) and one O(5) atom. In the fifth O site, O(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Te(1) atom. In the sixth O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one K(1) and two equivalent Te(1) atoms. In the seventh O site, O(3) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one Te(1) atom. In the eighth O site, O(4) is bonded to two equivalent K(1) and two equivalent Te(2) atoms to form distorted edge-sharing OK2Te2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
