The material described by V5O7 crystallizes in the orthorhombic Cmcm space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 14°. In the second V site, V(2) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 14°. In the third V site, V(3) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent V(3) atoms. In the second O site, O(1) is bonded to two equivalent V(2) and three equivalent V(1) atoms to form a mixture of distorted corner and edge-sharing OV5 square pyramids. In the third O site, O(2) is bonded in a trigonal non-coplanar geometry to one V(1) and two equivalent V(3) atoms. In the fourth O site, O(3) is bonded to one V(2), two equivalent V(1), and two equivalent V(3) atoms to form a mixture of corner and edge-sharing OV5 square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
