WZn4C22(N3O)4 crystallizes in the cubic Im-3m space group. W(1) is bonded to four equivalent O(1) atoms to form WO4 tetrahedra that share corners with four equivalent Zn(1)N3O tetrahedra. All W(1)-O(1) bond lengths are 1.72 Å. Zn(1) is bonded to one N(2), two equivalent N(1), and one O(1) atom to form ZnN3O tetrahedra that share  a cornercorner with one W(1)O4 tetrahedra. The Zn(1)-N(2) bond length is 1.98 Å. Both Zn(1)-N(1) bond lengths are 1.94 Å. The Zn(1)-O(1) bond length is 1.98 Å. There are four inequivalent C sites. In the first C site, C(4) is bonded in a distorted bent 150 degrees geometry to two equivalent N(1) atoms. Both C(4)-N(1) bond lengths are 1.21 Å. In the second C site, C(1) is bonded in a distorted single-bond geometry to one N(2) atom. The C(1)-N(2) bond length is 1.62 Å. In the third C site, C(3) is bonded in a bent 150 degrees geometry to two equivalent N(2) atoms. Both C(3)-N(2) bond lengths are 1.17 Å. In the fourth C site, C(2) is bonded in a single-bond geometry to one N(1) atom. The C(2)-N(1) bond length is 1.51 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted T-shaped geometry to one Zn(1), one C(2), and one C(4) atom. In the second N site, N(2) is bonded to one Zn(1), one C(3), and two equivalent C(1) atoms to form distorted corner-sharing NZnC3 tetrahedra. O(1) is bonded in a linear geometry to one W(1) and one Zn(1) atom. Linkers: 24 [C]1[C][N@]2[C][C][N@@]1[C]2 ,48 [C]1[C][N][C][N]1. Metal clusters: 12 [Zn]O[W](O[Zn])(O[Zn])O[Zn].
