The compound described by V2O3 is Corundum-like structured and crystallizes in the orthorhombic Pbca space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), two equivalent O(3), and three equivalent O(2) atoms to form a mixture of edge, corner, and face-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 47-62°. In the second V site, V(2) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form a mixture of edge, corner, and face-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 47-70°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one V(1) and three equivalent V(2) atoms to form a mixture of distorted edge and corner-sharing OV4 tetrahedra. In the second O site, O(2) is bonded to one V(2) and three equivalent V(1) atoms to form a mixture of distorted edge and corner-sharing OV4 trigonal pyramids. In the third O site, O(3) is bonded to two equivalent V(1) and two equivalent V(2) atoms to form a mixture of distorted edge and corner-sharing OV4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
