The crystal structure described by UMo5O16 crystallizes in the monoclinic P2 space group. U(1) is bonded to two equivalent O(4), two equivalent O(6), two equivalent O(8), and two equivalent O(9) atoms to form corner-sharing UO8 hexagonal bipyramids. There are three inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 6-coordinate geometry to one O(3), one O(5), one O(6), one O(8), and two equivalent O(2) atoms. In the second Mo site, Mo(2) is bonded in a 6-coordinate geometry to two equivalent O(4), two equivalent O(7), and two equivalent O(8) atoms. In the third Mo site, Mo(3) is bonded in a 6-coordinate geometry to one O(3), one O(4), one O(5), one O(6), and two equivalent O(1) atoms. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to two equivalent Mo(3) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent Mo(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Mo(1) and one Mo(3) atom.
