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

Lateral macrobicyclic compartmental mono and binuclear nickel(II) complexes were synthesized. Spectral, electrochemical and kinetic studies were carried out. Cyclic voltammetric studies show quasireversible one electron reduction waves both in cathodic and anodic region. The catalytic activities of the complexes towards hydrolysis of 4-nitrophenyl phosphate increase with macrocyclic ring size. Macrocyclic ring size influences the electrochemical (reduction) and catalytic properties of the complexes.
