Cu2V2O7 crystallizes in the monoclinic C2/c space group. V(1) is bonded in a 4-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. Cu(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(4), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent V(1) and one Cu(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent V(1) and one Cu(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one V(1) and two equivalent Cu(1) atoms. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Cu(1) atoms.
