Heterobismetal complexes of [26]hexaphyrin(1.1.1.1.1.1).
Au(III)Cu(III) and Au(III)Rh(I) heterobismetal complexes of meso-aryl-substituted [26]hexaphyrin were rationally prepared from a monometal Au(III) complex. The Au(III)Cu(III) complex is an aromatic molecule with a rectangular shape, while Au(III)Rh(I) complexes are out-of-plane macrocycles, being either aromatic or antiaromatic depending upon the number of conjugated pi electrons. The 26pi Au(III)Rh(I) complex was converted into an aromatic and planar 26pi Au(III)Rh(III) complex via double C-H bond activation upon refluxing in pyridine.
