CoV3O8 is quartz (alpha)-derived structured and crystallizes in the triclinic P1 space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(3), one O(7), and one O(8) atom to form VO4 tetrahedra that share corners with two equivalent V(3)O4 tetrahedra and corners with two equivalent Co(1)O4 tetrahedra. In the second V site, V(2) is bonded to one O(2), one O(4), one O(5), and one O(6) atom to form VO4 tetrahedra that share corners with two equivalent V(3)O4 tetrahedra and corners with two equivalent Co(1)O4 tetrahedra. In the third V site, V(3) is bonded to one O(3), one O(4), one O(5), and one O(7) atom to form corner-sharing VO4 tetrahedra. Co(1) is bonded to one O(1), one O(2), one O(6), and one O(8) atom to form CoO4 tetrahedra that share corners with two equivalent V(1)O4 tetrahedra and corners with two equivalent V(2)O4 tetrahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one Co(1) atom.
