The variation of the Fermi contact term has been analyzed for divalent copper complexes as a function of in-plane σ-covalent bonding. A model has been based on the spin polarization of the partially occupied 4s orbitals through a σ bond and a competition between σ bonds with different symmetries and has been used to explain why the Fermi contact term decreases toward both the covalent and the ionic limiting cases. Other theoretical models suggested previously to explain this behavior have also been examined, and the effects of distortion of the tetragonal symmetry have been analyzed.
