The compound described by VWN3 crystallizes in the triclinic P-1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one N(1), one N(4), one N(5), and one N(6) atom to form VN4 tetrahedra that share  a cornercorner with one W(2)N4 tetrahedra,  an edgeedge with one W(1)N6 octahedra, and  an edgeedge with one W(2)N4 tetrahedra. In the second V site, V(2) is bonded in a 4-coordinate geometry to one N(3), one N(4), and two equivalent N(1) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one N(1), one N(5), two equivalent N(2), and two equivalent N(3) atoms to form distorted WN6 octahedra that share corners with three equivalent W(2)N4 tetrahedra, edges with two equivalent W(1)N6 octahedra, and  an edgeedge with one V(1)N4 tetrahedra. In the second W site, W(2) is bonded to one N(2), one N(4), one N(5), and one N(6) atom to form WN4 tetrahedra that share corners with three equivalent W(1)N6 octahedra,  a cornercorner with one V(1)N4 tetrahedra, and  an edgeedge with one V(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 54-64°. There are six inequivalent N sites. In the first N site, N(1) is bonded in a distorted rectangular see-saw-like geometry to one V(1), two equivalent V(2), and one W(1) atom. In the second N site, N(2) is bonded in a distorted trigonal non-coplanar geometry to one W(2) and two equivalent W(1) atoms. In the third N site, N(3) is bonded in a T-shaped geometry to one V(2) and two equivalent W(1) atoms. In the fourth N site, N(4) is bonded in a distorted T-shaped geometry to one V(1), one V(2), and one W(2) atom. In the fifth N site, N(5) is bonded in a distorted T-shaped geometry to one V(1), one W(1), and one W(2) atom. In the sixth N site, N(6) is bonded in a bent 120 degrees geometry to one V(1) and one W(2) atom. is represented by the CIF file [CIF]
