The complex, which is planar, and a variety of its derivatives are carriers for O2 as well as oxidation catalysts.[2] Preparation and structureThe compound features square planar Co(II). It forms a variety of five-coordinate adducts, as is typical for complexes of d7 metals. In addition to oxygen and nitrogen donor sites provided by the salen2−, the metal typically is bound to pyridine (py) to give the complex Co(salen)(py). Such complexes bind O2 to give derivatives of the type (μ-O2)[Co(salen)py]2 and [Co(salen)py(O2)].[2] Salcomine is commercially available. It may be easily synthesized from cobalt(II) acetate and salenH2:[3] ApplicationsThe 1938 report that this compound reversibly bound O2 led to intensive research on salen and related ligands for the storage or transport of oxygen.[4] Salcomine catalyzes the oxidation of 2,6-disubstituted phenols by dioxygen.[5] References1. ^N,N′-Bis(salicylidene)ethylenediaminocobalt(II) at Sigma-Aldrich 2. ^1 Shoichiro Yamada “Advancement in stereochemical aspects of Schiff base metal complexes” Coordination Chemistry Reviews 1999, volume 190–192, 537–555. 3. ^{{cite journal | doi = 10.1021/ed054p443 | journal = J.
