The metalation of meso ‐tetrakis(pentafluorophenyl)‐substituted [26]rubyrin has been explored with Group 9 metal salts (Rh I , Co II , Ir III ), affording a Hückel aromatic [26]rubyrin–bis‐Rh I complex with a highly curved gable‐like structure, a Hückel antiaromatic [24]rubyrin–bis‐Co II complex that displays intramolecular antiferromagnetic coupling between the two Co II ions ( J =−4.5 cm −1 ), and two Cp*‐capped Ir III complexes; in one, the iridium metal sits on the [26]rubyrin frame with two IrN bonds, whereas the other has an additional IrC bond, although both Ir III complexes display moderate aromatic character. This work demonstrates characteristic metalation abilities of this [26]rubyrin toward Group 9 metals.
