NiOF2 crystallizes in the monoclinic P2_1/c space group. Ni(1) is bonded to one O(1), two equivalent F(1), and three equivalent F(2) atoms to form a mixture of distorted corner and edge-sharing NiOF5 octahedra. The corner-sharing octahedral tilt angles range from 17-23°. O(1) is bonded in a bent 120 degrees geometry to one Ni(1) and one O(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Ni(1) atoms. In the second F site, F(2) is bonded in a T-shaped geometry to three equivalent Ni(1) atoms.

The corner-sharing octahedral tilt angles range from 17-23°. The Ni(1)-O(1) bond length is 2.34 Å. Both Ni(1)-F(1) bond lengths are 1.94 Å. There are a spread of Ni(1)-F(2) bond distances ranging from 2.01-2.04 Å. O(1) is bonded in a bent 120 degrees geometry to one Ni(1) and one O(1) atom. The O(1)-O(1) bond length is 1.24 Å. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Ni(1) atoms. In the second F site, F(2) is bonded in a T-shaped geometry to three equivalent Ni(1) atoms.
