The crystal structure described by K2TeO6 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to two equivalent O(4) and four equivalent O(3) atoms to form a mixture of distorted edge and corner-sharing KO6 pentagonal pyramids. In the second K site, K(2) is bonded in a 9-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(4), and four equivalent O(3) atoms. Te(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1) and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted square co-planar geometry to two equivalent K(1) and two equivalent K(2) atoms. In the second O site, O(1) is bonded in a distorted water-like geometry to one K(2) and one Te(1) atom. In the third O site, O(2) is bonded in a bent 120 degrees geometry to one K(2) and one Te(1) atom. In the fourth O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent K(1) and two equivalent K(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
