“…On the opposite side, a shift to higher values of the ν(C-O) vibration bands of phenoxy groups was observed, corresponding to the simultaneous strengthening of the electronic density of these bonds and coordination of the oxygen atoms to the metallic center. These results are in good agreement with those reported for similar structures [54,55].…”

Salicylaldehyde, 2-hydroxyacetophenone, and 3,5-dichlorosalicylaldehyde react with 1,2-diaminoethane to give three symmetrical Schiff bases H 2 L 1 , H 2 L 2 , and H 2 L 3 , respectively. With Ru(III) ions, these ligands lead to three complexes: Ru(III)ClL 1 (1), Ru(III)ClL 2 (2), and Ru(III)ClL 3 (3). The purity of these compounds was estimated by TLC technique and microanalysis while their structures were supported by the usual spectroscopic methods such as NMR, infrared, and electronic spectra. The cyclic voltammetry in acetonitrile showed irreversible waves for all three ligands. Under the same experimental conditions, it was proved that the ruthenium is coordinated in the three complexes 1, 2, and 3 showing quasireversible redox systems. The behavior of these complexes and their comparison with cytochrome P450 are investigated using them as catalysts in the presence of molecular oxygen with an apical nitrogen base: 1-or 2-methylimidazole.

“…The free ligands exhibit the characteristic C=O band in 1613-1608 cm −1 region. The C=N stretching frequencies are in the 1566-1560 cm −1 region as reported for similar ligands [33,34]. The low energy position of the C=N band could be attributed to its involvement in conjugation with the aromatic system.…”

The synthesis of two new ligands 4,4'-(diphenylmethane-4,4'-diyldinitrilo)dipentan-2-one (H 2 L 1 ) and 4,4'-(diphenylether-4,4'-diyldinitrilo)dipentan-2-one (H 2 L 2 ) is reported. The ligands have two acetylacetone subunits separated by diphenylmethane or diphenylether group. The ligands form stable dinuclear complexes with Ni(II) and Cu(II) ions. Ligands and their complexes were characterized by elemental analysis, m.p., IR, molar conductivity and magnetic moment measurements. The interaction between these compounds with DNA has also been investigated by agarose gel electrophoresis, we found that the nickel(II) and copper(II) complexes can cleave supercoiled pBR322 DNA to nicked and linear forms. The copper(II) complexes with H 2 O 2 as a cooxidant exhibited the strongest cleaving activity. The free ligands were also characterized by 1 H NMR spectra.
