Reaction of Polymer-Heme Complexes with Molecular Oxygen

Reaction of Polymer-Heme Complexes with Molecular Oxygen 

Cobalt(II)-Schiff-base complexes with a nitrogenous base are also well known to bind molecular oxygen in an organic solvent at room temperature. 

But most of the Co(II) complexes react with molecular oxygen to yield binuclear dioxo-bridged species of the type (B)(S)Co-02-Co(SXB), and these may be readily oxidized to the corresponding super dioxo-bridged complexes, Co(III)—02 —Co(III). 

It is important to form a stable 1 1 dioxygen-metal complex, because oxyhemoglobin and oxymyoglobin are 1 1 dioxygen-iron complexes which can reversibly 

M(II)—02 and the dative structure, M(III)—02. So the second condition is that the oxygenated complex must be surrounded by a hydrophobic environment in order to suppress charge separation and to exclude water molecules from the vicinity of the oxygenated complex.
