The structure described by ZnMo8O10 crystallizes in the tetragonal I4_1md space group. There are four inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(4), two equivalent O(3), and two equivalent O(5) atoms to form MoO5 square pyramids that share corners with two equivalent Zn(1)O4 tetrahedra, edges with two equivalent Mo(1)O5 square pyramids, and edges with two equivalent Mo(2)O5 square pyramids. In the second Mo site, Mo(2) is bonded to one O(3), two equivalent O(2), and two equivalent O(4) atoms to form MoO5 square pyramids that share corners with two equivalent Zn(1)O4 tetrahedra, edges with two equivalent Mo(1)O5 square pyramids, and edges with two equivalent Mo(2)O5 square pyramids. In the third Mo site, Mo(3) is bonded in a rectangular see-saw-like geometry to one O(4), one O(5), and two equivalent O(1) atoms. In the fourth Mo site, Mo(4) 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 two equivalent O(2) and two equivalent O(5) atoms to form ZnO4 tetrahedra that share corners with four equivalent Mo(1)O5 square pyramids and corners with four equivalent Mo(2)O5 square pyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to two equivalent Mo(3) and two equivalent Mo(4) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mo(4), two equivalent Mo(2), and one Zn(1) atom. In the third O site, O(3) is bonded in a see-saw-like geometry to one Mo(2), one Mo(4), and two equivalent Mo(1) atoms. In the fourth O site, O(4) is bonded in a see-saw-like geometry to one Mo(1), one Mo(3), and two equivalent Mo(2) atoms. In the fifth O site, O(5) is bonded in a rectangular see-saw-like geometry to one Mo(3), two equivalent Mo(1), and one Zn(1) atom. is represented by the CIF card [CIF]
