Ligand-field calculations for cobalt(II) compounds
Abstract
g Factors are calculated for tetragonal low-spin d7 complexes using a d3 hole ligand-field model. It is shown that the unpaired electron lies in the dz2 orbital (i.e. that the ground state is Γ6 or 2A1) in all forms of cobalt phthalocyanine, as well as in vitamin B12r and its model compounds.
