The crystal structure described by K2NHS2O6 crystallizes in the monoclinic Cc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(6), two equivalent O(4), and two equivalent O(5) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to one O(4), one O(5), one O(6), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. N(1) is bonded in a distorted trigonal non-coplanar geometry to one H(1), one S(1), and one S(2) atom. H(1) is bonded in a single-bond geometry to one N(1) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded to one N(1), one O(2), one O(4), and one O(6) atom to form corner-sharing SNO3 tetrahedra. In the second S site, S(2) is bonded to one N(1), one O(1), one O(3), and one O(5) atom to form corner-sharing SNO3 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one S(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one K(1), two equivalent K(2), and one S(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one S(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one S(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one S(2) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
