The material described by CoV2O6 crystallizes in the triclinic P-1 space group. There are three inequivalent V sites. In the first V site, V(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(5), one O(8), and two equivalent O(6) atoms. In the second V site, V(2) is bonded to one O(4), one O(6), one O(7), and one O(8) atom to form VO4 tetrahedra that share  a cornercorner with one Co(1)O6 octahedra and  a cornercorner with one Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-51°. In the third V site, V(3) is bonded in a 6-coordinate geometry to one O(1), one O(5), one O(8), one O(9), and two equivalent O(7) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(2), one O(4), one O(5), one O(9), and two equivalent O(1) atoms to form CoO6 octahedra that share  a cornercorner with one V(2)O4 tetrahedra,  an edgeedge with one Co(1)O6 octahedra, and  an edgeedge with one Co(2)O6 octahedra. In the second Co site, Co(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with two equivalent V(2)O4 tetrahedra and edges with two equivalent Co(1)O6 octahedra. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one V(3) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one V(1), one Co(1), and one Co(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one Co(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one V(2), one Co(1), and one Co(2) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one V(1), 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(2) and two equivalent V(1) atoms. In the seventh O site, O(7) is bonded in a trigonal planar geometry to one V(2) and two equivalent V(3) atoms. In the eighth O site, O(8) is bonded in a distorted single-bond geometry to one V(1), one V(2), and one V(3) atom. In the ninth O site, O(9) is bonded in a bent 150 degrees geometry to one V(3) and one Co(1) atom. is represented by the CIF card [CIF]
