Graphical Abstract

Distanzierte Wechselwirkung: Antiferromagnetische Wechselwirkungen zwischen entfernten Kupfer(II)- und Silber(II)-Ionen treten nur bei dreifach und einfach verknüpften Diporphyrinen mit wenigstens einer β-β-Bindung auf, was die zentrale Bedeutung dieser direkten Bindung für eine antiferromagnetische Kopplung unterstreicht. Qualitativ erklären lassen sich die Befunde anhand der Spinverteilung in den Kupfer(II)- und Silber(II)-porphyrinen (siehe Bild).
