Stabilization of synthetic heme-superoxo complexes by hydrogen bonding: a still on-going quest

The design of various types of synthetic heme models has allowed the fine tuning of the location of hydrogen bond donors around the ferrous coordination site. Through the years, it has migrated from a lateral to a quasi-apical position. Still, the unambiguous existence of an actual H-bond with the dioxygen adduct remains to be established.
