The material structure described by WN2 is Brookite-like structured and crystallizes in the tetragonal P4_2/n space group. W(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing WN6 octahedra. The corner-sharing octahedral tilt angles range from 29-63°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to three equivalent W(1) atoms. In the second N site, N(2) is bonded in a 3-coordinate geometry to three equivalent W(1) atoms. is represented by the CIF file [CIF]
