CuWO3F2 crystallizes in the monoclinic P2_1/m space group. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent F(1) atoms to form corner-sharing WO4F2 octahedra. The corner-sharing octahedral tilt angles are 23°. Cu(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent F(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one W(1) and one Cu(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. F(1) is bonded in a distorted bent 120 degrees geometry to one W(1) and one Cu(1) atom.

The corner-sharing octahedral tilt angles are 23°. Both W(1)-O(1) bond lengths are 1.80 Å. There is one shorter (1.92 Å) and one longer (1.94 Å) W(1)-O(2) bond length. Both W(1)-F(1) bond lengths are 2.12 Å. Cu(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent F(1) atoms. Both Cu(1)-O(1) bond lengths are 1.87 Å. Both Cu(1)-F(1) bond lengths are 2.00 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one W(1) and one Cu(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. F(1) is bonded in a distorted bent 120 degrees geometry to one W(1) and one Cu(1) atom.
