The compound described by LiWN2 is Caswellsilverite-like structured and crystallizes in the trigonal R3m space group. Li(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. W(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form edge-sharing WN6 octahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Li(1) and three equivalent W(1) atoms to form a mixture of distorted edge, corner, and face-sharing NLi3W3 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 0-45°. In the second N site, N(2) is bonded to three equivalent Li(1) and three equivalent W(1) atoms to form a mixture of edge, corner, and face-sharing NLi3W3 octahedra. is represented by the CIF card [CIF]
