title: Group 9 Metal Complexes of meso-Aryl-Substituted Rubyrin.
abstract: 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 IrN bonds, whereas the other has an additional IrC bond, although both Ir(III) complexes display moderate aromatic character. This work demonstrates characteristic metalation abilities of this [26]rubyrin toward Group 9 metals.
