The material described by KNO2 crystallizes in the orthorhombic Imm2 space group. K(1) is bonded to one N(1) and six equivalent O(1) atoms to form distorted KNO6 pentagonal bipyramids that share corners with eight equivalent K(1)NO6 pentagonal bipyramids, corners with two equivalent O(1)K3N tetrahedra, and edges with two equivalent K(1)NO6 pentagonal bipyramids. N(1) is bonded in a distorted trigonal planar geometry to one K(1) and two equivalent O(1) atoms. O(1) is bonded to three equivalent K(1) and one N(1) atom to form distorted OK3N tetrahedra that share  a cornercorner with one K(1)NO6 pentagonal bipyramid, corners with twelve equivalent O(1)K3N tetrahedra, and edges with two equivalent O(1)K3N tetrahedra. is represented by the CIF card [CIF]
