Lateral macrobicyclic compartmental mono and binuclear nickel(II) complexes derived from phenolate ligands: Synthesis, spectral, electrochemical and kinetic studies

Mononuclear metal complexes with ciprofloxacin: Synthesis, characterization and DNA-binding properties

“…The existence of two m(Mo = O) absorptions for the MoO 2þ 2 complex is indicative of a cis arrangement of the two oxygen atoms around Mo atom [50]. The band at 3400-3420 cm À1 in the IR spectra of the complexes (1), (3) and (4) can be attributed to m(O-H) vibration of the coordinated water molecules [40].…”

“…[Ni I ]. Considering all the above processes and taking into account the literature [50], the complete pattern of the redox behavior of complex (4) could be described in the following equations: (Fig. 6D).…”

Nickel-diflunisal complexes: synthesis, characterization, in vitro antioxidant activity and interaction with DNA and albumins

“…Upon scanning towards negative potentials, two cathodic waves appeared at E pc1 and E pc2 which were followed by two anodic waves at E pa2 and E pa1 . According to the literature, these two irreversible waves may be assigned to the redox couples Ni(II)/Ni(I) (E pc1 and E pa1 ) and Ni(I)/Ni(0) (E pc2 and E pa2 ) [68,69]. Compound 1 crystallizes in the triclinic space group Pī.…”

Characterization and DNA-interaction studies of 1,1-dicyano-2,2-ethylene dithiolate Ni(II) mixed-ligand complexes with 2-amino-5-methyl thiazole, 2-amino-2-thiazoline and imidazole. Crystal structure of [Ni(i-MNT)(2a-5mt)2]

“…3B-C) and the corresponding redox potentials are given in Table 3. Considering all the above processes and taking into account the literature, 32 Transition metal complexes can bind to DNA via covalent and/ or noncovalent interactions. 35,36 In covalent binding mode, a labile ligand of the complexes is usually replaced by a nitrogen base of DNA such as guanine N7.…”
