The material described by KNO2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 7-coordinate geometry to one N(1), three equivalent O(1), and three equivalent O(2) atoms. N(1) is bonded in a 3-coordinate geometry to one K(1), one O(1), and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent K(1) and one N(1) atom. In the second O site, O(2) is bonded to three equivalent K(1) and one N(1) atom to form distorted corner-sharing OK3N tetrahedra. is represented by the CIF file [CIF]
