Iron porphyrins can act as potent electrocatalysts for CO 2 functionalization. The catalytically active species has been proposed to be a formal Fe(0) porphyrin complex, [Fe(TPP)] 2- (TPP = tetraphenylporphyrin), generated by two-electron reduction of [Fe II (TPP)]. Our combined spectroscopic and computational investigations reveal that the reduction is ligand-centered and that [Fe(TPP)] 2- is best formulated as an intermediate-spin Fe(II) center that is antiferromagnetically coupled to a porphyrin diradical anion, yielding an overall singlet ground state. As such, [Fe(TPP)] 2- contains two readily accessible electrons, setting the stage for CO 2 reduction.
