Revisiting the Electronic Ground State of Copper Corroles

Abstract

Back in the saddle: Copper corroles do not contain a CuIII ion, but rather a well-hidden CuII 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.
