NiZnF4 crystallizes in the triclinic P-1 space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted square co-planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. In the second Ni site, Ni(2) is bonded in a distorted square co-planar geometry to two equivalent F(3) and two equivalent F(4) atoms. Zn(1) is bonded in a body-centered cubic geometry to two equivalent F(1), two equivalent F(2), two equivalent F(3), and two equivalent F(4) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one Ni(1) and two equivalent Zn(1) atoms. In the second F site, F(2) is bonded in a 3-coordinate geometry to one Ni(1) and two equivalent Zn(1) atoms. In the third F site, F(3) is bonded in a 4-coordinate geometry to one Ni(1), one Ni(2), and two equivalent Zn(1) atoms. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to one Ni(2) and two equivalent Zn(1) atoms.
