The material structure described by W2ZnO5 crystallizes in the orthorhombic Cmcm space group. W(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), and three equivalent O(2) atoms. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing ZnO6 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent W(1) and two equivalent Zn(1) atoms to form distorted corner-sharing OZn2W2 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent W(1) and one Zn(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one W(1) and one Zn(1) atom. is represented by the CIF card [CIF]
