The synthesis of Co(III) complexes with the new linear pentadentate ligands meso-, and racemic 2,6-bis(3-carboxy-1,2-dimethyl-2-azapropyl)pyridine (1 and 1b), respectively, and 2,6-bispyridine (2) are described.Only one of the different possible isomers is obtained from each ligand.The structure of the complexes has been assigned on the basis of their 1H-NMR and CD spectra.The structure of the aqua-cobalt(III)-1a and the aqua-cobalt(III)-1b has been confirmed by X-ray analysis.Partial resolution of optical antipodes of the aqua-cobalt(III)-1b was achieved by column chromatography and a tentative assignment of their absolute configuration is made.
