Berhanu Degagsa, Gezahegn Faye*, Nester Fernandez
ABSTRACT
The complex, [Cu(C6H12N4)3(H2O)3]SO4, has been synthesized in a
mixed solvent of water and ethanol. It has been characterized by
Infrared and Electronic Spectra, Magnetic Susceptibility, Melting Point
and Conductivity measurement. Quantitatively, Copper ion, Sulphate
ion and HMTA in the complex were determined with the help of Flame
Atomic Absorption Spectroscopy, Gravimetric and Volumetric
Analysis respectively. The study results suggested distorted octahedral
complex in which the central metal ion, Cu (II), is bonded to three
water and three HMTA ligands. The ligand, HMTA, is active against
Pseudomonas aeruginosa and Salmonella typhi while it is inactive
against Staphylococcus aureus and Escherichia coli. But, the complex
is active against all the four tested bacteria species. Specially, the
complex showed greater activity than the reference antibiotic, gentamycin, against
Staphylococcus aureus and Salmonella typhi.
