d8-metal complexes under strong field conditions stabilize the dz 2-electrons by lowering their coordination symmetry from octahedral to tetragonal or even square planar. That means, two negative ligands are removed until they disappear from the coordination sphere. But in the crystal lattice, there may be a further increase of dz 2-stabilization by approaching positive charges. It is, in fact, a continuous process from lifting two opposite negative charges from the octahedral complex to infinity, till bringing back two positive charges on the same way. in this picture, the “ free” square planar complex is only an intermediate form in the series
  • octahedral — negative tetragonal — square planar — positive tetragonal

  • coordination. Thus, under strong field conditions, the most stable stacking of square planar complexes may be the columnar type as in the Magnus’ green salt and in the vic-dioximes.
