NiF6(NF4)2 is Fluorite structured and crystallizes in the tetragonal I4/m space group. The structure is zero-dimensional and consists of four tetrafluoroammonium molecules and two NiF6 clusters. In each NiF6 cluster, Ni(1) is bonded in an octahedral geometry to six equivalent F(2,3) atoms. F(2,3) is bonded in a single-bond geometry to one Ni(1) atom.

In each NiF6 cluster, Ni(1) is bonded in an octahedral geometry to six equivalent F(2,3) atoms. There are two shorter (1.78 Å) and four longer (1.79 Å) Ni(1)-F(2,3) bond lengths. F(2,3) is bonded in a single-bond geometry to one Ni(1) atom.
