| Popis: | Cobalt(II) complexes have been prepared with ligands derived from salicylaldehyde (or a substituted salicylaldehyde) and bis(2-aminoethyl)amine. These compounds are designated Co(RSALDIEN) and represent an unusual situation in which one of the donor atoms is not coordinated to the metal. As a result, tetrahedral complexes are observed which are very hygroscopic. These compounds also react with dioxygen to produce an irreversible paramagnetic dioxygen adduct. It is believed that the imine group remains uncoordinated in the oxygenated complex, thus giving the first example of a five-coordinate cobalt dioxygen complex. |
