Robust Bis-rhodium(I) complex of π-extended planar, anti-aromatic hexaphyrin[1.0.1.0.1.0]

β,β’-phenylene bridged hexaphyrin[1.0.1.0.1.0] (naphthorosarin), an expanded porphyrin possessing C3v-symmetry, has been shown to possess unique electronic features. We now report a bimetallic Rh(I)-complex of naphthorosarin retaining 24 π-antiaromatic characteristics. The two Rh(I) cations reside on opposite sides of the macrocyclic π-system and are separated at a distance consistent with a possible Rh(I)-Rh(I) metallic bond interaction
