The crystal structure described by K2H6TeSO10 crystallizes in the triclinic P-1 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(4), one O(5), one O(6), and one O(7) atom. In the second K site, K(2) is bonded to one O(10), one O(2), one O(4), one O(5), one O(7), one O(8), and two equivalent O(9) atoms to form distorted KO8 hexagonal bipyramids that share  a cornercorner with one Te(1)O6 octahedra, corners with two equivalent Te(2)O6 octahedra,  a cornercorner with one S(1)O4 tetrahedra,  an edgeedge with one K(2)O8 hexagonal bipyramid,  an edgeedge with one Te(2)O6 octahedra, and  an edgeedge with one S(1)O4 tetrahedra.
