Copper(II) Supramolecular Complex: Synthesis, Crystal Structure, and Electrochemical Property

Abstract

A novel complex {Cu(Bobb) 2 ](pic) 2 } 2 [pic = picrate anion, Bobb = 1,3-bis(1-benzylbenzimidazol-2-yl)-2-oxopropane] was synthesized and characterized by means of elemental analyses and electrical conductivity. The crystal structure of the copper complex has been determined by single-crystal X-ray diffraction. A study of the electrochemistry of the title compound was carried out by using cyclic voltammetry. It revealed that the copper complex exhibits a quasi-reversible redox process. The X-ray structure of the above complex shows

Synthesis, structure, DNA-binding properties, and antioxidant activity of copper(II) and cobalt(II) complexes with bis(N-allylbenzimidazol-2-ylmethyl)benzylamine

“…In previous studies [11][12][13][14], we have investigated that the coordinating ability of various benzimidazole ligands. In this study, the synthesis, characterization, and DNA-binding activities of two transition metal complexes with bis(Nallylbenzimidazol-2-ylmethyl)benzylamine are presented.…”

Synthesis, crystal structure, electrochemistry and antioxidative activity of copper(II), manganese(II) and nickel(II) complexes containing bis(N‐ethylbenzimidazol‐2‐ylmethyl)aniline

“…The separation between the cathodic and anodic peak potentials, Δ E p , and the current i pa / i pc indicate a quasi‐reversible redox process assignable to the Cu(II)/Cu(I) couple . The neutral free Etbba ligand proves not to be electroactive over the range −1.2 to +1.2 V. According to previous reports, a transition metal complex must have a redox potential below 0.65 V ( E °(O 2 –O 2 − )) and above −0.33 V ( E °(O 2 –O 2 − )) in order to be an effective mimic of SOD, so toxic singlet oxygen cannot be formed. The redox potential of 0.1067 V shows that complex 1 has SOD activity.…”

Four‐, five‐ and six‐coordinated transition metal complexes based on naphthalimide Schiff base ligands: Synthesis, crystal structure and properties

“…The separation between the cathodic and anodic peak potentials Δ E p ( E pa − E pc ) is greater than 60 mV, and the current i pa / i pc > 1, indicating an electrochemically irreversible process which can be assigned to the Cu(II)/Cu(I) couple . The neutral uncomplexed Schiff base ligands are not electroactive over the range − 1.5 to +1.5 V. According to previous reports, a transition metal complex must have a redox potential below 0.65 V ( E° (O 2 –O 2 − )) and above −0.33 V ( E° (O 2 –O 2 − )) such that catalysis can be an effective mimic of SOD but toxic singlet oxygen cannot be formed; so the redox potential 0.272 V shows that 1 may have SOD activity.…”
