FVO2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(4), one F(1), and one F(2) atom. In the second V site, V(2) is bonded in a distorted trigonal bipyramidal geometry to one O(1), one O(2), one O(4), one F(1), and one F(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one V(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one V(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to one V(1) and one V(2) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom.
