CsNiF3 crystallizes in the hexagonal P6_3/mmc space group. Cs(1) is bonded in a trigonal planar geometry to three equivalent F(1) atoms. Ni(1) is bonded to six equivalent F(1) atoms to form face-sharing NiF6 octahedra. F(1) is bonded in a 3-coordinate geometry to one Cs(1) and two equivalent Ni(1) atoms.
