The structure described by K2TeSO10 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 distorted body-centered cubic geometry to one O(10), one O(3), one O(5), one O(6), one O(8), one O(9), and two equivalent O(4) atoms. In the second K site, K(2) is bonded to one O(10), one O(2), one O(3), one O(6), one O(7), one O(9), and two equivalent O(1) atoms to form distorted KO8 hexagonal bipyramids that share  a cornercorner with one Te(2)O6 octahedra, corners with two equivalent Te(1)O6 octahedra,  a cornercorner with one S(1)O4 tetrahedra,  an edgeedge with one K(2)O8 hexagonal bipyramid,  an edgeedge with one Te(1)O6 octahedra, and  an edgeedge with one S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 33-48°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TeO6 octahedra that share corners with four equivalent K(2)O8 hexagonal bipyramids and edges with two equivalent K(2)O8 hexagonal bipyramids. In the second Te site, Te(2) is bonded to two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms to form TeO6 octahedra that share corners with two equivalent K(2)O8 hexagonal bipyramids. S(1) is bonded to one O(10), one O(7), one O(8), and one O(9) atom to form SO4 tetrahedra that share  a cornercorner with one K(2)O8 hexagonal bipyramid and  an edgeedge with one K(2)O8 hexagonal bipyramid. There are ten inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent K(2) and one Te(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one K(2) and one Te(1) atom. In the third 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 fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Te(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one K(1) and one Te(2) atom. In the sixth 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 seventh O site, O(7) is bonded in a distorted single-bond geometry to one K(2) and one S(1) atom. In the eighth O site, O(8) is bonded in a distorted single-bond geometry to one K(1) and one S(1) atom. In the ninth O site, O(9) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one S(1) atom. In the tenth O site, O(10) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one S(1) atom. is represented by the CIF card [CIF]
