Structural, electrochemical characterization and SOD mimic activities of 1D chain or 3D network encouraged by unique μ 2 -bridging by adipate ion in mixed ligand complexes containing α-diimine as auxiliary ligand

The present ternary complexes [Cu(ada)(phen)(H 2 O)] ·2H 2 O (1), [Co 2 (ada) 2 (phen) 2 (H 2 O) 2 ] (2) and [{Cu(ada) 3 (bipy)} n ·3nH 2 O] (3) (H 2 ada = adipic acid, phen = 1,10-phenanthroline and bipy = 2,2′-bipyridine) obtained under varying experimental conditions were characterized by spectra...
