The material described by WN2 is Keatite-like structured and crystallizes in the orthorhombic Pna2_1 space group. W(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing WN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the second N site, N(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. is represented by the CIF card [CIF]
