WZnO2 crystallizes in the triclinic P-1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. In the second W site, W(2) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(4) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 4-coordinate geometry to one O(1), one O(4), and two equivalent O(3) atoms. In the second Zn site, Zn(2) is bonded in a distorted T-shaped geometry to one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one W(2), two equivalent W(1), and one Zn(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one W(1), two equivalent W(2), and one Zn(2) atom. In the third O site, O(3) is bonded to one W(1), one Zn(2), and two equivalent Zn(1) atoms to form distorted corner-sharing OZn3W tetrahedra. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent W(2), one Zn(1), and one Zn(2) atom.
