ZnMo8O10 crystallizes in the tetragonal I4_1/amd space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to two equivalent O(2) and three equivalent O(3) atoms to form MoO5 square pyramids that share corners with two equivalent Zn(1)O4 tetrahedra and edges with four equivalent Mo(1)O5 square pyramids. In the second Mo site, Mo(2) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. Zn(1) is bonded to four equivalent O(2) atoms to form ZnO4 tetrahedra that share corners with eight equivalent Mo(1)O5 square pyramids. There are three inequivalent O sites. In the first O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mo(2), two equivalent Mo(1), and one Zn(1) atom. In the second O site, O(1) is bonded in a square co-planar geometry to four equivalent Mo(2) atoms. In the third O site, O(3) is bonded in a see-saw-like geometry to one Mo(2) and three equivalent Mo(1) atoms.

In the first Mo site, Mo(1) is bonded to two equivalent O(2) and three equivalent O(3) atoms to form MoO5 square pyramids that share corners with two equivalent Zn(1)O4 tetrahedra and edges with four equivalent Mo(1)O5 square pyramids. Both Mo(1)-O(2) bond lengths are 2.18 Å. There is one shorter (2.16 Å) and two longer (2.17 Å) Mo(1)-O(3) bond lengths. In the second Mo site, Mo(2) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. The Mo(2)-O(2) bond length is 2.14 Å. The Mo(2)-O(3) bond length is 2.17 Å. Both Mo(2)-O(1) bond lengths are 2.21 Å. Zn(1) is bonded to four equivalent O(2) atoms to form ZnO4 tetrahedra that share corners with eight equivalent Mo(1)O5 square pyramids. All Zn(1)-O(2) bond lengths are 2.05 Å. There are three inequivalent O sites. In the first O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mo(2), two equivalent Mo(1), and one Zn(1) atom. In the second O site, O(1) is bonded in a square co-planar geometry to four equivalent Mo(2) atoms. In the third O site, O(3) is bonded in a see-saw-like geometry to one Mo(2) and three equivalent Mo(1) atoms.
