Abstract

Mixed-ligand chelate complexes of cobalt(111) of the type (β-diketone)Co(salen) have been synthesized using replacement reactions of the coba1t(111) species XCo(salen) (X = halogen, alkyl group; salen = tetradentate Schiff-base ligand) by the appropriate β-diketone, or its sodium or thallium(1) salt. Studies of their infrared, N.M.R.,and mass spectra point to the formation of cis oxygen-bonded β-diketone chelates, in which the salen group adopts an unusual twisted configuration.
