VO2 is Hydrophilite-like structured and crystallizes in the monoclinic P2_1/c space group. There are two inequivalent V sites. In the first V site, V(1) 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 range from 21-57°. In the second V site, V(2) 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 range from 21-57°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one V(2) and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one V(1) and two equivalent V(2) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one V(2) and two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent V(2) atoms.

The corner-sharing octahedral tilt angles range from 21-57°. The V(1)-O(2) bond length is 2.00 Å. The V(1)-O(4) bond length is 1.99 Å. There is one shorter (1.90 Å) and one longer (1.98 Å) V(1)-O(1) bond length. There is one shorter (1.88 Å) and one longer (2.02 Å) V(1)-O(3) bond length. In the second V site, V(2) 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 range from 21-57°. The V(2)-O(1) bond length is 1.98 Å. The V(2)-O(3) bond length is 2.06 Å. There is one shorter (1.80 Å) and one longer (2.06 Å) V(2)-O(2) bond length. There is one shorter (1.90 Å) and one longer (1.99 Å) V(2)-O(4) bond length. There are four inequivalent O sites.
