A hexa-aza-macrocyclic compound of high thermal stability is readily obtained from 2,9-diamino-1,10-phenanthroline by its thermolysis or by its condensation with 2,9-dihalogeno-1,10-phenanthroline. The structure of this macrocycle has been established as a conjugated system of a novel type, related to some extent to porphin and phthalocyanin. The macrocyclic compound forms copper, cobalt, and nickel complexes.
