(AuCuIII)-Cu-III and (AuRhI)-Rh-III heterobismetal complexes of meso-aryl-substituted [26]hexaphyrin were rationally prepared from a monometal Au-III complex. The (AuCuIII)-Cu-III complex is an aromatic molecule with a rectangular shape, while (AuRhI)-Rh-III complexes are out-of-plane macrocycles, being either aromatic or antiaromatic depending upon the number of conjugated pi electrons. The 26,7 (AuRhI)-Rh-III complex was converted into an aromatic and planar 26 pi (AuRhIII)-Rh-III complex via double C-H bond activation upon refluxing in pyridine.
