KN2 crystallizes in the orthorhombic Immm space group. K(1) is bonded to eight equivalent N(1) atoms to form KN8 hexagonal bipyramids that share corners with eight equivalent N(1)K4N square pyramids and edges with twelve equivalent K(1)N8 hexagonal bipyramids. N(1) is bonded to four equivalent K(1) and one N(1) atom to form distorted NK4N square pyramids that share corners with four equivalent K(1)N8 hexagonal bipyramids, corners with sixteen equivalent N(1)K4N square pyramids, and edges with six equivalent N(1)K4N square pyramids.

K(1) is bonded to eight equivalent N(1) atoms to form KN8 hexagonal bipyramids that share corners with eight equivalent N(1)K4N square pyramids and edges with twelve equivalent K(1)N8 hexagonal bipyramids. There are four shorter (2.88 Å) and four longer (3.03 Å) K(1)-N(1) bond lengths. N(1) is bonded to four equivalent K(1) and one N(1) atom to form distorted NK4N square pyramids that share corners with four equivalent K(1)N8 hexagonal bipyramids, corners with sixteen equivalent N(1)K4N square pyramids, and edges with six equivalent N(1)K4N square pyramids. The N(1)-N(1) bond length is 1.19 Å.
