STRUCTURE OF MOLECULAR COMPOUNDS OF PORPHINE

The bonds of the cyclic system of porphine molecules have an effect on the properties and characteristics of these molecules. Complexes obtained from porphines have an effect on the spectral properties of the components. The highest spectral changes are observed in Fe-porphines, since they form particularly strong complexes when interacting with CO, pyridine and water. The singly charged ions of porphines are represented by short-lived intermediate compounds. They can quickly transition to doubly charged ions, since their structures are unstable and one of the central N atoms is not equivalent to the remaining atoms.
