Three new ternary copper(II) complexes formulated as (Cu(HIda)(bipy)) 1; (Cu(HIda)(phen)) 2; (Cu(HIda)(dmp)) 3; where HIda =N-(2-hydroxyethyl)-2- iminodiacetic acid ; bipy = 2, 2'- bipyridine; phen = 1,10- phenanthroline; dmp = 2,9-dimethyl 1,10-phenanthroline, have been synthesized and characterized by partial elemental analysis, FAB-mass (m/z), EPR, UV-visible and CV measurements. The magnetic and spectroscopic data of all these complexes 1-3 indicate distorted octahedral geometry. The EPR spectra of these complexes in frozen DMSO solutions showed a single at g ca. 2. The trend in g-value (g||>g>2.0023) suggests that the unpaired electron on copper (II) has dx2-y2 character. The SOD activities of the complexes have been investigated. Antibacterial and antifungal activity of these complexes were also measured and discussed.
