The material described by V2O5 crystallizes in the orthorhombic Pnma space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(4), and two equivalent O(3) atoms. In the second V site, V(2) is bonded in a tetrahedral geometry to one O(1), one O(4), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one V(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
