The crystal structure described by UVH3O7 crystallizes in the monoclinic P2_1/c space group. U(1) is bonded to one O(1), one O(2), one O(6), two equivalent O(4), and two equivalent O(5) atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent U(1)O7 pentagonal bipyramids, corners with two equivalent V(1)O5 trigonal bipyramids,  an edgeedge with one U(1)O7 pentagonal bipyramid, and edges with two equivalent V(1)O5 trigonal bipyramids.

There are three inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(5) and one O(7) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(6) and one O(7) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(7) atom. There are seven inequivalent O sites. In the first O site, O(4) is bonded in a 3-coordinate geometry to two equivalent U(1) and one V(1) atom. In the second O site, O(5) is bonded to two equivalent U(1), one V(1), and one H(1) atom to form distorted corner-sharing OU2VH tetrahedra. In the third O site, O(6) is bonded in a distorted bent 150 degrees geometry to one U(1) and one H(2) atom. In the fourth O site, O(7) is bonded in a trigonal non-coplanar geometry to one H(1), one H(2), and one H(3) atom.
