The reversible oxygen uptake by coordination compounds
mimics the behaviour
of natural oxygen carriers such as hemoglobin.
(i) Discuss the interaction between molecular oxygen and the iron centre in
(ii) The reaction between Co(Salen) and molecular oxygen in a 1: 1 ratio results
in a paramagnetic product. However, when the Co(Salen) is in excess, the
product formed is diamagnetic. Explain briefly.
