ZnW4O9 crystallizes in the tetragonal P4/n space group. The structure consists of two 7440-66-6 atoms inside a W4O9 framework. In the W4O9 framework, W(1) is bonded to one O(1), two equivalent O(2), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-25°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to four equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded in a distorted T-shaped geometry to three equivalent W(1) atoms.

The corner-sharing octahedral tilt angles range from 0-25°. The W(1)-O(1) bond length is 2.29 Å. There is one shorter (1.93 Å) and one longer (1.95 Å) W(1)-O(2) bond length. There are a spread of W(1)-O(3) bond distances ranging from 2.07-2.11 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to four equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms.
