The material structure described by CrWN2 is Caswellsilverite-like structured and crystallizes in the trigonal R3m space group. W(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. Cr(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form edge-sharing CrN6 octahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent W(1) and three equivalent Cr(1) atoms to form a mixture of edge, face, and corner-sharing NCr3W3 octahedra. In the second N site, N(2) is bonded to three equivalent W(1) and three equivalent Cr(1) atoms to form a mixture of distorted edge, face, and corner-sharing NCr3W3 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 0-45°. is represented by the CIF card [CIF]
