The material structure described by KN3 crystallizes in the tetragonal I4/mcm space group. K(1) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form corner-sharing KN6 octahedra. The corner-sharing octahedral tilt angles range from 0-75°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to two equivalent K(1) and one N(1) atom. In the second N site, N(2) is bonded in a linear geometry to two equivalent K(1) atoms. is represented by the CIF file [CIF]
