The material described by K2NS2O6 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. N(1) is bonded in a bent 120 degrees geometry to two equivalent S(1) atoms. S(1) is bonded to one N(1), one O(1), one O(2), and one O(3) atom to form corner-sharing SNO3 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent K(1) and one S(1) atom. is represented by the CIF card [CIF]
