UMo2O8 crystallizes in the orthorhombic Pban space group. U(1) is bonded to two equivalent O(1) and four equivalent O(5) atoms to form a mixture of distorted corner and edge-sharing UO6 octahedra. The corner-sharing octahedral tilt angles are 4°. Mo(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(4), one O(5), and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(6) is bonded in a distorted linear geometry to two equivalent Mo(1) atoms. In the second O site, O(1) is bonded in a linear geometry to two equivalent U(1) atoms. In the third O site, O(2) is bonded in a linear geometry to two equivalent Mo(1) atoms. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Mo(1) atoms. In the fifth O site, O(4) is bonded in a linear geometry to two equivalent Mo(1) atoms. In the sixth O site, O(5) is bonded in a trigonal planar geometry to two equivalent U(1) and one Mo(1) atom.

The corner-sharing octahedral tilt angles are 4°. Both U(1)-O(1) bond lengths are 2.07 Å. There are two shorter (2.24 Å) and two longer (2.27 Å) U(1)-O(5) bond lengths. Mo(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(4), one O(5), and two equivalent O(6) atoms. The Mo(1)-O(2) bond length is 1.90 Å. The Mo(1)-O(3) bond length is 1.96 Å. The Mo(1)-O(4) bond length is 1.95 Å. The Mo(1)-O(5) bond length is 2.03 Å. There is one shorter (1.74 Å) and one longer (2.41 Å) Mo(1)-O(6) bond length. There are six inequivalent O sites.
