The crystal structure described by CoV3O8 crystallizes in the orthorhombic Iba2 space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form VO4 tetrahedra that share corners with three equivalent V(2)O6 octahedra and corners with three equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-68°. In the second V site, V(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(7) atom to form distorted VO6 octahedra that share  a cornercorner with one Co(1)O6 octahedra, corners with three equivalent V(1)O4 tetrahedra, and edges with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 39°. In the third V site, V(3) is bonded in a 5-coordinate geometry to one O(5), one O(7), one O(8), and two equivalent O(6) atoms. Co(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(8) atom to form CoO6 octahedra that share  a cornercorner with one V(2)O6 octahedra, corners with three equivalent V(1)O4 tetrahedra, and edges with two equivalent V(2)O6 octahedra. The corner-sharing octahedral tilt angles are 39°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(2) and one Co(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one V(1), one V(2), and one Co(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one V(1), one V(2), and one Co(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one V(1), one V(2), and one Co(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one V(2), one V(3), and one Co(1) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one V(1) and two equivalent V(3) atoms. In the seventh O site, O(7) is bonded in a linear geometry to one V(2) and one V(3) atom. In the eighth O site, O(8) is bonded in a distorted linear geometry to one V(3) and one Co(1) atom. is represented by the CIF card [CIF]
