Abstract
The interest in the magnetic interactions among metal atoms in polymeric transition-metal complexes is increasing,” from both an experimental and a theoretical point of view. By far, the most common examples of reported complexes are those where an even number of electrons are present. Recently, we reported the synthesis and the characterization of some mixed-valence nickel complexes with the ligand 1,8- naphthyridine (napy),12 where a copper acetate-type dimer is present containing three unpaired electrons. We report now the single-crystal ESR spectra of one of these complexes and interpret the magnetic interactions between the metal ions using an angular overlap parameterization of the orbital energies we have suggested re~ent1y.l~File | Dimensione | Formato | |
