VHO2 crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 56°. In the second V site, V(2) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one V(1) and two equivalent V(2) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one V(2) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to one V(1), two equivalent V(2), and one H(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one V(2), two equivalent V(1), and one H(2) atom.
