PURPOSE: To provide binuclear metal macrocyclic and macrobicyclic complexes for oxygen separation and transport and a method for extracting oxygen from a gaseous mixture contg. the oxygen.
CONSTITUTION: The binuclear metallic complex which has a metallic complex ligand formed with the ligand by the reaction of dialdehyde and primary polyamine and is reversibly reactable with oxygen molecules. The method of (a) bringing the binuclear metallic complex which has the metallic complex ligand formed with the ligand formed by the reaction of the dialdehyde and the primary polyamine and is capable of reversibly reacting with oxygen molecules into contact with the gaseous mixture contg. the oxygen to form the dioxygen adduct with the binuclear metallic complex and (b) releasing the substantially pure oxygen from the dioxygen binuclear metallic complex adduct.
