Description
Summary:Macrocyclic Cu^sup II^ compounds of the type Cu(L^sub 4^)Cl^sub 2^ (where L^sub 4^ = N^sub 4^ or N^sub 2^O^sub 2^ donor macrocyclic ligand) have been synthesized by treating the corresponding macrocycles with copper chloride in methanol. These compounds were characterized with the help of elemental analysis, i.r., mass, ESR, electronic spectra, conductance, magnetic and thermal studies. Distorted octahedral geometry has been proposed for all of these compounds. These compounds were found to be efficient in the catalytic oxidation of ascorbic acid and the percentage yields of oxidation products were determined spectrophotometrically. The biological activities of these compounds have been tested against gram +ve and gram -ve bacteria and found to be more active when compared with commercially available antibacterials like streptomycin and ampicillin.[PUBLICATION ABSTRACT]
