Potassium Tetrafluoridenickelate(II) is structurally related to perovskite. It can be thought of as containing single slices from the perovskite structure sharing four F- atoms from the octahedra within the layer and having terminal F atoms above and below the layer. These layers are separated by K+ ions and are displaced relative to one another.
