The structure described by V2O5 crystallizes in the monoclinic C2/c space group. V(1) is bonded to one O(3), two equivalent O(1), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 27-56°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to three equivalent V(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms. is represented by the CIF file [CIF]
