The material structure described by WN2 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent W sites. In the first W site, W(1) is bonded to one N(1), one N(3), one N(4), and one N(6) atom to form corner-sharing WN4 tetrahedra. In the second W site, W(2) is bonded to one N(1), one N(2), one N(4), and one N(5) atom to form corner-sharing WN4 tetrahedra. In the third W site, W(3) is bonded to one N(2), one N(3), one N(5), and one N(6) atom to form corner-sharing WN4 tetrahedra. There are six inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one W(2) and one W(3) atom. In the third N site, N(3) is bonded in a bent 120 degrees geometry to one W(1) and one W(3) atom. In the fourth N site, N(4) is bonded in a bent 120 degrees geometry to one W(1) and one W(2) atom. In the fifth N site, N(5) is bonded in a bent 150 degrees geometry to one W(2) and one W(3) atom. In the sixth N site, N(6) is bonded in a bent 120 degrees geometry to one W(1) and one W(3) atom. is represented by the CIF file [CIF]
