Low-spin nitrato iron complexes were formed by sequential reactions of oxygen and ammonia with thin layers of an iron porphyrin complex at low temperatures (80–100 K). Tigran Kurtikyan from the National Academy of Sciences in Armenia and Peter Ford from the University of California in the US, believe that the kinetic barrier for such isomerisations must be quite low, regardless of the reaction mechanism used.
