<jats:title>Abstract</jats:title><jats:p>The reaction of [{Ir(cod)(μ‐Cl)}<jats:sub>2</jats:sub>] and K<jats:sub>2</jats:sub>CO<jats:sub>3</jats:sub> or of [{Ir(cod)(μ‐OMe)}<jats:sub>2</jats:sub>] alone with the non‐natural tetrapyrrole 2,2′‐bidipyrrin (H<jats:sub>2</jats:sub>BDP) yields, depending on the stoichiometry, the mononuclear complex [Ir(cod)(HBDP)] or the homodinuclear complex [{Ir(cod)}<jats:sub>2</jats:sub>(BDP)]. Both complexes react readily with carbon monoxide to yield the species [Ir(CO)<jats:sub>2</jats:sub>(HBDP)] and [{Ir(CO)<jats:sub>2</jats:sub>}<jats:sub>2</jats:sub>(BDP)], respectively. The results from NMR spectroscopy and X‐ray diffraction reveal different conformations for the tetrapyrrolic ligand in both complexes. The reaction of [{Ir(coe)<jats:sub>2</jats:sub>(μ‐Cl)}<jats:sub>2</jats:sub>] with H<jats:sub>2</jats:sub>BDP proceeds differently and yields the macrocyclic [4e<jats:sup>−</jats:sup>,2H<jats:sup>+</jats:sup>]‐oxidized product [IrCl<jats:sub>2</jats:sub>(9‐Meic)] (9‐Meic = monoanion of 9‐methyl‐9,10‐isocorrole), which can be addressed as an iridium analog of cobalamin.</jats:p>
