文摘

A new metal complex of Cd(II), Mn(II) and Fe(III) derived from potassium 2-carbomethoxy amino-5-trithiocarbonate 1,3,4-thiadiazole (CATT) and potassium 2-N(4-N,N-dimethylaminobenzyliden)-4-trithiocarbonate1,3,4-thiadiazole (DBTT), has been synthesized. Structural features of these complexes were obtained in the solid state by several techniques using flame atomic absorption, elemental analyses C, H, N and S, FT-IR, UV-vis spectra, thermal analyses TGA, conductivity and magnetic susceptibility measurements. Spectral data suggest an octahedral structure around the metal ion except cadmium (II) complexes that have tetrahedral geometry. The antibacterial activity of ligands and their metal complexes in vitro against the microorganisms: Pseudomonas aeruginosa (as gram negative strain bacteria) and Staphylococcus aureus (as gram positive strain bacteria) was examined using two different concentrations (10 and 5 mM) in nutrient agar media and some complexes showed noticeable activity against the tested microorganisms comparaing them to ampicillin as the standard drug.
