“…X-ray diffraction and vibrational and EPR spectroscopic studies eventually allowed the distinction to be made between superoxo and peroxo ligands. Several dicobalt(III) complexes with a superoxo ion as the only bridging unit were crystallographically characterized, − and other superoxo-bridged dicobalt complexes had either an additional μ-amido , or a μ-hydroxo bridge. In these doubly bridged dicobalt complexes, the resulting five-membered rings were almost flat.…”

“…Dicobalt(III) complexes involving peroxide (O 2 2− ) [19,23,24] or superoxide as the only bridging unit were crystallographically characterized [25][26][27][28][29]. But other dioxygen-bridged dicobalt complexes also had an additional µ-amido or µ-hydroxo bridge [30][31][32].…”

Two peroxo-bridged dinuclear Co(III) complexes, {[Co 2 (ea) 2 (Phen) 2 (O 2 )]·5.5H 2 O·2Cl} (1) and {[Co 2 (ea) 2 (Bipy) 2 (O 2 )]·2H 2 O·2NO 3 } (2) (Hea = ethanolamine, Phen = 1,10-phenanthroline, Bipy = 2,2′-bipyridine), are prepared by reaction of CoCl 2 ·6H 2 O or Co(NO 3 ) 2 ·6H 2 O with Hea in presence of an α-diimine (Phen or Bipy) under reflux. The complexes have been characterized by IR, NMR, TGA, cyclic voltammetric, PXRD and single crystal XRD techniques. Single crystal X-ray crystallographic investigations of 1 and 2 reveal that each Co(III) is coordinated by one deprotonated ethanolamine and an α-diimine chelate. The remaining coordination sites of the metal ions are satisfied by bridging peroxide (O 2 2-) in a cis-µ-1,2 manner. The distances [O-O = 1.487(6) (1) and 1.462(3) Å (2) and CoˑˑˑCo = 2.731(12) (1) and 2.7426(6) Å (2)] support the peroxo bridging in a cis manner in both complexes. The crystal lattice is consolidated via extensive H-bonding and π-π interactions to form a 3D supramolecular architecture. Thermal data are consistent with the proposed stoichiometry and presence of lattice water. The cyclic voltammetric studies of 1 indicate the presence of a quasi reversible redox couple (Co III -Co III /Co II -Co II ) in solution. Genotoxic studies are also performed on 1 to investigate the possible applications and side effects of the compounds in medicine.
