validated the corresponding CoII complexes as synthetic model systems for dioxygen‐binding heme proteins and demonstrated the structural requirements for proper distal H‐bonding to CoII‐bound dioxygen. Here, we systematically vary the H‐bond donor ability of the distal heterocycles, as predicted based on pKa values. The H‐bond in the dioxygen adducts of the CoII porphyrins was directly measured by Q‐band
