Back in the saddle : Copper corroles do not contain a Cu III ion, but rather a well‐hidden Cu II ion. A comparative crystallographic and theoretical study (see spin‐density representation) of isostructural corroloid complexes with copper ions in different formal oxidation states suggests that the divalent state is stabilized through a saddling distortion of the corrole ligand.
