KNSO4 crystallizes in the orthorhombic P2_12_12_1 space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. N(1) is bonded in a water-like geometry to one S(1) and one O(1) atom. S(1) is bonded in a tetrahedral geometry to one N(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(1) atom.
