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).
