摘要

Dielectric and conductivity properties of cobalt(II), nickel(II), and copper(II)-imidazole-2-carboxaldehyde-glycylglycine (imal-glygly) complexes have been studied using impedance spectroscopy. The dielectric constant and dielectric loss factor for metal complexes have been analyzed in the frequency range from 1 Hz to 1 MHz at room temperature. The a.c. conductivity result reveals that these complexes exhibit dissimilar frequency dependent conductivity. An attempt has been made to investigate the relaxation and conductivity studies, since there are fairly few literatures available.
