V2O3 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(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted VO5 trigonal bipyramids that share corners with three equivalent V(2)O6 octahedra, corners with four equivalent V(1)O5 trigonal bipyramids, and edges with three equivalent V(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-78°. In the second V site, V(2) is bonded to one O(2), two equivalent O(1), and three equivalent O(3) atoms to form distorted VO6 octahedra that share corners with two equivalent V(2)O6 octahedra, corners with three equivalent V(1)O5 trigonal bipyramids, edges with three equivalent V(2)O6 octahedra, and edges with three equivalent V(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 33°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent V(1) and two equivalent V(2) atoms to form a mixture of edge and corner-sharing OV4 trigonal pyramids. In the second O site, O(2) is bonded in a trigonal planar geometry to one V(2) and two equivalent V(1) atoms. In the third O site, O(3) is bonded to one V(1) and three equivalent V(2) atoms to form a mixture of edge and corner-sharing OV4 trigonal pyramids.

The corner-sharing octahedral tilt angles range from 47-78°. The V(1)-O(3) bond length is 2.11 Å. There is one shorter (2.03 Å) and one longer (2.05 Å) V(1)-O(1) bond length. There is one shorter (1.96 Å) and one longer (2.00 Å) V(1)-O(2) bond length. In the second V site, V(2) is bonded to one O(2), two equivalent O(1), and three equivalent O(3) atoms to form distorted VO6 octahedra that share corners with two equivalent V(2)O6 octahedra, corners with three equivalent V(1)O5 trigonal bipyramids, edges with three equivalent V(2)O6 octahedra, and edges with three equivalent V(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 33°. The V(2)-O(2) bond length is 1.97 Å. There is one shorter (2.09 Å) and one longer (2.18 Å) V(2)-O(1) bond length. There are two shorter (1.97 Å) and one longer (2.15 Å) V(2)-O(3) bond length. There are three inequivalent O sites.
