Simple dimer containing dissociatively stable mono-imidazole ligated ferrohemes

Qing-Zheng Yang, Daria Khvostichenko, John D. Atkinson and Roman Boulatov

In weakly coordinating solvents FeII meso-(N-methylimidazol-2-yl)porphine 1Fe exists as a stable dimer (Kd = 50 ± 30 nM) that binds ligands without undergoing dissociation and is presently the simplest complex in which the mono-imidazole ligation of a ferroheme is enforced without excess imidazole in solution.
