(Figure Presented) Interaction over a distance: Long-range antiferromagnetic interactions between distant copper(II) and silver(II) ions are observed only for triply and singly linked diporphyrins with at least one β-β bond, which underscores the critical importance of this direct bond for antiferromagnetic coupling. These results can be qualitatively accounted for in terms of the spin distribution of copper(II) and silver(II) porphyrins (see picture).
