NiF3 crystallizes in the trigonal R-3 space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to six equivalent F(1) atoms to form corner-sharing NiF6 octahedra. The corner-sharing octahedral tilt angles are 42°. In the second Ni site, Ni(2) is bonded to six equivalent F(1) atoms to form corner-sharing NiF6 octahedra. The corner-sharing octahedral tilt angles are 42°. F(1) is bonded in a bent 150 degrees geometry to one Ni(1) and one Ni(2) atom.
