Calculation of dissociation constants showed the tightest binding with a Ba2+ ion. Density functional theory calculations were used to elucidate the effects of redox inactive cations toward the electronic structures of Fe complexes. Although the Fe–NNN complexes, both in the absence and presence of cations, can catalyze C–H oxidation of 9,10-dihydroanthracene, to give anthracene [hydrogen atom transfer (HAT)
