The material described by V4O7 crystallizes in the triclinic P-1 space group. There are four inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(4), one O(6), and one O(7) atom to form corner-sharing VO4 tetrahedra. In the second V site, V(2) is bonded to one O(1), one O(7), and two equivalent O(5) atoms to form a mixture of edge and corner-sharing VO4 tetrahedra. In the third V site, V(3) is bonded to one O(3), one O(4), and two equivalent O(1) atoms to form a mixture of edge and corner-sharing VO4 tetrahedra. In the fourth V site, V(4) is bonded in a distorted trigonal planar geometry to one O(2), one O(3), and one O(6) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(2) and two equivalent V(3) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one V(1) and one V(4) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one V(3) and one V(4) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one V(1) and one V(3) atom. In the fifth O site, O(5) is bonded in an L-shaped geometry to two equivalent V(2) atoms. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one V(1) and one V(4) atom. In the seventh O site, O(7) is bonded in a distorted bent 150 degrees geometry to one V(1) and one V(2) atom. is represented by the CIF card [CIF]
