The crystal structure described by CrN is Halite, Rock Salt structured and crystallizes in the monoclinic C2/m space group. Cr(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form a mixture of corner and edge-sharing CrN6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent N sites. In the first N site, N(1) is bonded to six equivalent Cr(1) atoms to form a mixture of corner and edge-sharing NCr6 octahedra. The corner-sharing octahedral tilt angles range from 2-3°. In the second N site, N(2) is bonded to six equivalent Cr(1) atoms to form a mixture of corner and edge-sharing NCr6 octahedra. The corner-sharing octahedral tilt angles range from 2-3°. is represented by the CIF card [CIF]
