Three cobalt(II) complexes, bis-(salicylaldehyde)-ethylenediimine-cobalt(II), bis-(salicylaldimino) cobalt(II), and di-(salicylal)-3,3′-diimino-di-n-propylamine-cobalt(II), were mixed with poly-4-vinylpyridine. These mixtures showed ESR signals which reversively appeared under oxygen. We tried to identify these signals on the basis of the electonic structure, cobalt(III)-O2−1. The oxygenation-deoxygenation rates were also observed and found to obey the Elovich rate equation.
