U(HO)8 crystallizes in the monoclinic C2/c space group. U(1) is bonded to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms to form distorted edge-sharing UO8 hexagonal bipyramids. There are four inequivalent H sites. In the first H site, H(1) is bonded in a distorted linear geometry to one O(3) and one O(4) atom. In the second H site, H(2) is bonded in a distorted linear geometry to one O(3) and one O(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(4) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(1) and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent U(1), one H(4), and one O(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one U(1) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one U(1), one H(1), and one H(2) atom. In the fourth O site, O(4) is bonded in a distorted water-like geometry to one H(1), one H(2), one H(3), and one H(4) atom.
