From: A pyridinic Fe-N4 macrocycle models the active sites in Fe/N-doped carbon electrocatalysts
The (phen2N2)H2 macrocycle was synthesized by the reaction of 2,9-dichloro-1,10-phenanthroline with anhydrous ammonia. The (phen2N2)FeCl model complex was obtained by treatment of (phen2N2)H2 with FeCl3 in the presence of N(n-Bu)3 under an inert atmosphere. Continuously washing (phen2N2)FeCl with hot ethanol for 48 hours using a Soxhlet apparatus yielded the [(phen2N2)Fe]2O model complex.
