V2HO4 crystallizes in the monoclinic Cm space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(3), one O(5), two equivalent O(1), and two equivalent O(2) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. In the second V site, V(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form a mixture of distorted corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. In the third V site, V(3) is bonded to one O(4), one O(6), two equivalent O(1), and two equivalent O(2) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. H(1) is bonded in a single-bond geometry to one O(1) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one V(1), one V(2), one V(3), and one H(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one V(1), one V(2), and one V(3) atom.
