The material described by K2N2SO5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and three equivalent O(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted bent 120 degrees geometry to one N(2) and one O(4) atom. In the second N site, N(2) is bonded in a distorted trigonal planar geometry to one N(1), one S(1), and one O(2) atom. S(1) is bonded in a tetrahedral geometry to one N(2), one O(3), and two equivalent O(1) atoms. There are four 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 four equivalent K(1) and one N(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to four equivalent K(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to four equivalent K(1) and one N(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
